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