My suspicion is that this relates to differences in when each compiler
uses excess precision, given that it's only for 32-bit and only for float
and double not long double.
This does illustrate that when we regenerate the x86 / x86_64 ulps from
scratch (which I think we should do at the start of the release freeze) it
will be desirable to have not just people with different processors but
also people with different GCC versions running the tests and adding ulps
they see but other people don't.
