Hmm.  I've just gotten through glibc testing and there are quite a few failures
of the form

Failure: nearbyint (4.5): Exception "Inexact" set

in math/test-double.out.

Any chance you can run the glibc math tests against real hardware and see if
these pass?  I have a feeling that qemu is now signaling inexact when the
hardware doesn't for "/SU" (but not /SUI) instructions.
