flac: fix build issues with e500v2 (gnuspe) toolchain

For a PPC target flac will try to build with altivec optimizations.
Altivec and SPE are mutually exclusive options.  Between flac's
configure choices and the ppce500v2 tune file options we'd end up with
a compile invocation with the following arguments:

-mabi=spe -mspe -mabi=altivec -maltivec

Which would cause the compile to fail due to the mutual exclusion.

Pulled in a patch from the debian SPE port that addresses this issue:

+Subject: [PATCH] No AltiVec on SPE
+
+Consider *gnuspe which matches powerpc-unknown-linux-gnuspe where
+AltiVec is not available at all. This triplet uses SPE which is
+incompatible with AltiVec shares the same opcode range and can't be used
+at all.
