I can't put it in the buildfarm ;-) but I have access to real s390
hardware inside Red Hat. I'll try to run a test build and see whether
the regression tests pass.
I would expect that s390 floating point is not even remotely
IEEE-compliant; they'd have stuck with the S/360 behavior which predates
the IEEE spec by probably 20 years. Whether it's worth generating
variant regression files for this arch, I don't know.
