Being able to build a nativesdk gcc is useful, particularly in cases
where the host compiler may be of an incompatible version (or a 32
bit compiler is needed).
Sadly, building nativesdk-gcc is not straight forward. We install
nativesdk-gcc into a relocatable location and this means that its
library locations can change. "Normal" sysroot support doesn't help
in this case since the values of paths like "libdir" change, not just
base root directory of the system.
In order to handle this we do two things:
a) Add %r into spec file markup which can be used for injected paths
such as SYSTEMLIBS_DIR (see gcc_multilib_setup()).
b) Add other paths which need relocation into a .gccrelocprefix section
which the relocation code will notice and adjust automatically.
This patch adds tweaks to the relocation script to handle the
new section too.

Fix an issue on a multilib configuration that contains more then 1 multilib.
I.e. on MIPS64:
DEFAULTTUNE = "mips64"
MULTILIBS = "lib32n:mips64_n32 lib32:mips32"
While normally you'd use 'libn32', the above is legal.
With the startswith code, the system will look to expand the 'lib32' element
and find the 'lib32n' instead, and will result in a warning:
lib32 doesn't have a corresponding tune. Skipping...

MULTILIB_OPTIONS takes the parameters which trigger a given multilib to be
selected. It supports *one* option per multilib, '/' separated. Spaces
separate options used to generate additional multilib combinations.
Adding in all of CFLAGS to this is therefore clearly a really bad idea
but how do we fix things?
The best option I've come up with so far is a list of whitelist variables
to use to trigger the multilibs. Its populated with the standard multilibs
we support, anyone setting up an advanced multilib can populate the variable
with the correct trigger parameters.
This has the advantage of simplifying the code and allowing us to remove
the code filtering blocks since there is no longer option duplication. Testing
after this change shows a much improved sdk toolchain functionality.

* GLIBC_DYNAMIC_LINKER64 reglex does not work for rs6000/linux64.h,
update it.
* it turns out that UCLIBC_DYNAMIC_LINKER reglex will strip the 32/64
chars from UCLIBC_DYNAMIC_LINKER64/UCLIBC_DYNAMIC_LINKER32, add '\b'.

We need to handle the UCLIBC_* linker variables in the same way
as we do the GLIBC_* ones to allow uclibc multilib to work properly.

Duplicate parameters in the tune args are repeated in the
MULTILIB_OPTIONS variable. This leads to incorrect configurations
if the order of the parameters is bad.
(Eg. "mhard-float m32/mhard-float m64" leads to an incorrect config)
This patch finds the common parameters and removes the duplicates.

These have been deprecated for a long time, convert the remaining
references to the correct modules and prepare for removal of the
compatibility support from bitbake.
