Hi,
vlc FTBFS on powerpcspe[1] like this:

As you can see above, -mtune=G4 is used by default, leading to the above
illegal instructions. The attached patch fixes this by enabling altivec only on
powerpc _except_ powerpcspe, and doing "confflags += --with-tuning=8548" which
is propagated to gcc as "-mtune=8548" on powerpcspe.
Thanks,
Roland
