For some unknown reason at Steven Rostedt added in disabling of the SPE
instruction generation for e500 based PPC cores in commit
6ec562328fda585be2d7f472cfac99d3b44d362a.
We are removing it because:
1. It generates e500 kernels that don't work
2. its not the correct set of flags to do this
3. we handle this in the arch/powerpc/Makefile already
4. its unknown in talking to Steven why he did this

A straight cherry pick of 65ecc14a30ad21bed9aabdfd6a2ae1a1aaaa6a00 causes
merge issues with 2.6.27.x, so there here is a version of the commit that
should apply to 2.6.27.x
