I have experienced the same issue on AMD64. It seems to be cause by -ffast-math being enabled in -Ofast. Adding -fno-fast-math to my CFLAGs eliminated the issue.
I've found -O2 also can prevent compilation. -O1 worked.

I have done several builds on amd64 for 2.0.14-r3, my findings: I'm unable to reproduce any issue with only -O2. I can reproduce the failure with only -Ofast, and make it pass using -Ofast -fno-fast-math.
