Subject: [PATCH][for 2.6.27/stable] Remove -mno-spe flags as they dont belong

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

Greg,

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
