Configuring gcc with --enable-target-optspace (which causes gcc to
append "-g -Os" to the default CFLAGS_FOR_TARGET and so force libgcc
etc target libraries to always be optimised for size) dates back to
the very first commit in oe-core git in 2005 (for gcc 3.4.3).
Configuring gcc with --enable-target-optspace is not done widely
elsewhere (it's not used for Ubuntu or Fedora host gcc, the Linaro
binary toolchain or in Buildroot since early 2015). Sometime around
gcc 4.5.x it caused problems for powerpc and so was disabled for that
architecture:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=43810
This patch removes --enable-target-optspace completely (ie powerpc is
no longer a special case) and allows optimisation of libgcc etc to be
controlled directly by the flags present in TARGET_CFLAGS.

It turns out writing the same list of packaging tasks multiple
times in multiple places is error prone. Move this to a new class
'nopackages", migrate existing users and add glibc-initial and
libgcc-initial since we don't want packages for those recipes.
This means the sstate for those recipes won't be installed, saving
small amounts of build time and bandwidth.
A reference to the old package_write task is also dropped.

When a project is configure to use sstate cache and has the host tool sysroot
cleaned, gcc-cross-initial may fail to be configured due to lack of
gnu-configize tool.
gcc-cross-initial recipe has autotools dependency inhibited, and the same flag
variable also excludes the gnu-config-native. Though there is an indirect
dependency through libmpc-native, it's not safe with sstate cache being used.
Moreover, gnu-config-native requires a perl package from autoconf-native to
run, otherwise it will fail with "Can't locate Autom4te/ChannelDefs.pm in @INC"
message.
This patch makes both dependencies explicit for gcc-cross-initial's
configuration.

The gcc default, bss-plt, will cause errors when using the prelinker. All
other distributions that I am aware of are using the the secure-plt. For an
explanation of the differences, the gcc docs:
Current PowerPC GCC accepts a `-msecure-plt' option that generates code
capable of using a newer PLT and GOT layout that has the security
advantage of no executable section ever needing to be writable and no
writable section ever being executable. PowerPC ld will generate this
layout, including stubs to access the PLT, if all input files (including
startup and static libraries) were compiled with `-msecure-plt'.
`--bss-plt' forces the old BSS PLT (and GOT layout) which can give
slightly better performance.
The security of the new PLT and ability to run the prelinker outweigh
any performance penalty.
The secure-plt is enabled by default. The old bss-plt can be enabled by
selecting 'bssplt' in the DISTRO_FEATURES.

Various pieces of the code assume that the --sysroot option gets passed
into the compiler tools. By having a "sane" default, we don't always
spot when this occurs and this can later show up as breakage in sstate,
or in usage of the external toolchain.
We've long since talked about poisoning the default such that it will
break unless the correct option is specified. This patch does just that.
If this patch causes something to fail to build, it most likely means
the various compiler flags and commands are not correctly being passed
through to the underlying piece of software and that there is a real
problem that needs fixing, its not the fault of this patch.

musl e.g. is configured to not use fixed-include
which is an improvement btw. but libgcc-initial configure
has tests which probe for limits.h and since we put
it in include-fixed/ dir and that dir does not appear
in gcc's internal default search path the configure tests
for CPP detection fail and libgcc-initial can not be compiled.

We already indicate our intentions to use ld.bfd by
specifying it in configure using --with-ld which works
ok unless here where we manually create symlinks to
binutils-cross components, when we use ld-is-gold feature
default ld points to gold and this symlinking has to be
aware of the fact that we configured binutils and gcc-cross to use
gold as default ld but gcc-cross-initial uses BFD ld
This would be visible when using gold and rebuilding
eglibc

If we don't do this, a stale limits.h may be detected in STAGING_DIR_TARGET
which would result in a different limits.h getting generated by gcc-cross-initial
that references it. The referenced limits.h will then not get found by eglibc-initial
causing rather strange build failures.
The simplest solution is to create a temporary sysroot containing only the things
gcc-cross-initial should care about and this results in a correct limits.h file
regardless of what else may have been built.

currently gcc installs a limits.h which references to another
limits.h which it expects from target sysroot and that header
in target sysroot will come from eglibc. So we need to break
this catch-22 and hence we install a self sufficient limits.h
which is then happy when referenced and doesnt complain about
missing limits.h from target sysroot.
This is mostly used when eglibc-initial configure is run

If EXTRA_OECONF_FPU is left set, certain ARM variables related to hard-float
can get pulled in and trigger rebuilds of the crosssdk code. The best solution
is to simply force the variable to a known correct value for the SDK targets
currently supported in the same way as TARGET_FPU.
There is some slight rearrangement of the gcc code to ensure the variable is
always used to call the fpu function.

for gcc 4.7/trunk since now libstdc++ needs access to build tree

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

This patch turns off nls and cleans up some of the dependencies resulting
in a slightly less convoluted set of build dependencies.

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.
