gcc: Enable SPE & AltiVec generation on powepc*linux target.

Browse Source 
[ADT bug #5761] -- https://bugzilla.yoctoproject.org/show_bug.cgi?id=5761

Also this patch adds symlinks to libgcc such that a GCC configured
by passing the target parameter without LIBCEXTENSION and ABIEXTENSION
specifiers to find the correct startup files from a libgcc configured
with these variables.

Subject: [PATCH] Enable SPE & AltiVec generation on powepc*linux target
When is configured with --target=powerpc-linux, the resulting GCC will
not be able to generate code for SPE targets (e500v1/v2).
GCC configured with --target=powerpc-linuxspe will not be able to
generate AltiVec instructions (for e6500).
This patch modifies the configured file such that SPE or AltiVec code
can be generated when gcc is configured with --target=powerpc-linux.
The ABI and speciffic instructions can be selected through the
"-mabi=spe or -mabi=altivec" and the "-mspe or -maltivec" parameters.
Upstream-Status: Inappropriate [configuration]
