Re: Regenerate x86 and x86_64 ulps

I'm not clear on the question.  Compilers configured with a range of 
different -march= settings and similar optimizations should all work for 
building glibc so testing with them is useful, and testing on a range of 
processors is also useful because of the multiarch variants of functions.  
-mfpmath=sse on 32-bit x86 is riskier, however, and I don't know if glibc 
built with it would work correctly.
