This was introduced by commit 2446151974, but it
fails in a minimal SPL build where the only thing in arch/powerpc/lib is
cache.c, which apparently doesn't generate any fixup records.
The problem is reported to occur with GCC 3.x, so insist on GCC 4.0 or newer.
Patterned after checkthumb as suggested by Tom Rini.
