This was introduced by commit 244615197469dd6fe75ae082f38424b97c79aeaf, 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.
