This was needed because on eglibc based builds we did not
define USE_NLS but now we define it in default config to have
a valid value so we do not need this here. Moreover it was
wrong and was not covering all cases of uclibc triplets

this option by default points to /usr/local no matter
what so we cant let it sit on sidelines otherwise it
will access host machine's /usr/local which may not
be desired. So disable this option. This also helps in making
gcc's shared state more consistent

When building gcc-cross-canadian libgcc is built using
headers from gcc-crosssdk and not the target sysroot
because we do not pass proper CFLAGS for target bits
so it ends up using CFLAGS that were meant for compiling
canadian gcc itself. It does not show up as a problem
when building SDK with eglibc because eglibc-nativesdk
and eglibc have identical headers. The problem shows
up clearly when you try to build uclibc based meta-toolchain
since then nativesdk libc and target libc are different

Currently we have a problem in our cross compiler since we use
/usr/include/c++ to be default gxx-include-dir and then expect
the patch we did to do the relocation w.r.t. sysroot however it
does not quite work so and we end up gxx-include-dirs not respecting
sysroot. A small test case would be
tst-unique4.cc
and it would fails like
tst-unique4.cc:1:18: fatal error: cstdio: No such file or directory
compilation terminated.
weather we use --sysroot or not it does not matter
arm-oe-linux-gnueabi-g++ -S tst-unique4.cc
--sysroot=/home/kraj/work/angstrom/sources/openembedded-core/build/tmp-eglibc/sysroots/qemuarm
failed in same way.
so we redo the GPLUSPLUS_INCLUDE_DIR_with_sysroot.patch based on upstream
submitted patch which tries to relocate the gxx-include-dir and to
achieve the relocation it has to be specified w.r.t to --with-sysroot
directory. e.g.
--with-sysroot=${SYSROOT}
--with-gxx-include-dir=${SYSROOT}/usr/include/c++
if we configure gcc like above then it becomes relocatable when
we run the compiler and specify --sysroot=<blah> then g++ will search
for gxx-headers under <blah>/usr/include/c++
if sysroot is not defined then it will use the default sysroot
and gxx-include-dir will be w.r.t. default sysroot.
Tested on qemuarm
/arm-oe-linux-gnueabi-g++ -S tst-unique4.cc
--sysroot=/home/kraj/work/angstrom/sources/openembedded-core/build/tmp-eglibc/sysroots/qemuarm

Right now for cross recipes e.g. gcc-cross and binutils-cross
we specify --disable-nls .... --enable-nls on configure cmdline
the --enable-nls coming from gettext bbclass.
So we disable nls for all cross inheriting recipes in gettext
bbclass and then we remove the extra --disable-nls in gcc-cross
and binutils-cross
This patch needs testing. Please help

We force the C locale when running builds for determinstic error messages. We
therefore have no need to NLS support in binutils cross or gcc cross.
We also don't need the standard base/autotools dependencies for our
toolchain components since we don't autoreconf these.
This patch turns off nls and cleans up some of the dependencies resulting
in a slightly less convoluted set of build dependencies.

This patched is derived from Richard, make gcc use the shared source
directory during the different building:
1) Make gcc-cross, gcc-cross-initial, gcc-cross-intermediate and
gcc-runtime share the same source directory.
2) The source directory is ${TMPDIR}/work-shared/gcc-${PV}, for example:
tmp/work-shared/gcc-4.5.1
3) Fix do_clean to clean the shared source directory and stamps
4) gcc uses sed and creates config files against ${S} which means the
directory should not be shared. Change the way to make it work:
* The configure option --with-headers=${STAGING_DIR_TARGET}${SYSTEMHEADERS}
can replace the sed command, see the code in configure:
if test "x$with_headers" != x; then
glibc_header_dir=$with_headers
This has the same effect as the sed command:
sed -i 's:^\([ ]*\)glibc_header_dir=\"${with_build_sysroot}/usr/include\": ...
so add the --with-headers=${STAGING_DIR_TARGET}${SYSTEMHEADERS} to
gcc-configure-cross.inc( not add to gcc-configure-common.inc, since
not all the gcc building need this, the one which has its own do_configure
doesn't need it).
* Move t-oe from ${T} to ${B}/gcc, so that the patched Makefile.in
can read it easily, please see the commit for gcc-4.5.1 and
gcc-4.6.0.
* Use the defaults.h in ${B}/gcc instead of ${S}/gcc, and the patched
configure.ac(configure) can read it correctly, please see the
commit for gcc-4.5.1 and gcc-4.6.0.
* The gcc-crosssdk.inc used sed to edit ${S}/config/*/linux*.h
to change the GLIBC_DYNAMIC_LINKER, which made the source
incompatible. To make the source compatible:
- Use:
sed -i ${S}/gcc/config/*/linux*.h -e \
's#\(GLIBC_DYNAMIC_LINKER[^ ]*\)\( *"/lib.*\)#\1 SYSTEMLIBS_DIR\2#'
so entries in the files that look like:
#define GLIBC_DYNAMIC_LINKER64 "/lib64/ld-linux-x86-64.so.2"
would become
#define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2"
and we define SYSTEMLIBS_DIR in defaults.h.
NOTE:
#define GLIBC_DYNAMIC_LINKER64 (SYSTEMLIBS_DIR "/ld-linux-x86-64.so.2")
doesn't work in in the following define:
#define LINUX_DYNAMIC_LINKER \
CHOOSE_DYNAMIC_LINKER (GLIBC_DYNAMIC_LINKER, UCLIBC_DYNAMIC_LINKER)
so use
#define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2"
5) Add do_configure_prepend to gcc-configure-common.inc and remove the
one in gcc-crosssdk.inc, this makes it easy to share the source,
otherwise we need do extra changes in gcc-configure-sdk.inc.
6) Use "cat > file <_EOF" to replace the "echo > file"

libgcc can link against the libc and libc can be dynamically renamed
so we ensure we package after libc. There was code in the gcc core
for this in the ipk case but it wasn't moved as part of the libgcc
split, this change fixes that oversight.

So far c++ include path is not relative to "--sysroot", which brings
trouble if we want to use the toolchain in a new environment where
the original build directory generating that toolchain is not
available. It's firstly exposed in multiple SDK sysroots support, and
then in the case when sstate packages are used, where c++ standard
headers are missing because gcc tries to search original build dir.
This patch makes c++ include path now relative to "--sysroot", and
then once "--sysroot" is assigned correctly in new environment, c++
include paths can be searched as expected.

Having one monolithic packages directory makes it hard to find things
and is generally overwhelming. This commit splits it into several
logical sections roughly based on function, recipes.txt gives more
information about the classifications used.
The opportunity is also used to switch from "packages" to "recipes"
as used in OpenEmbedded as the term "packages" can be confusing to
people and has many different meanings.
Not all recipes have been classified yet, this is just a first pass
at separating things out. Some packages are moved to meta-extras as
they're no longer actively used or maintained.
