cross-canadian/libgcc-common: Fixes for arm multilib

Browse Source 
Arm is unusual in that we force it to "linux-gnueabi" and "linux" doesn't
build. This was causing problems for multilib configurations which were assuming
"linux" was the default compiler rather than linux-gnueabi.

This change does two things, ensures symlinks are generated for linux-gnueabi
and also adapts the libgcc code to account for the difference on arm.

It still needs to immediately expand/save TARGET_VENDOR but we defer
deciding what TARGET_OS should be until we know TARGET_ARCH (which the
multilib code may change).

[YOCTO #8642]

Note that sanity tests of a 32 bit arm multilib still break due to issues
with the kernel headers on a mixed bit system. This looks to be a general
headers issue for the platform though and a different type of bug.

(From OE-Core rev: bcddc3e7eff138add031bc9c9728be5a42fa62ef)
