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]
