On a hardware (3A5000-7A2000-EVB) the test passes with the same GCC.  My
first guess would be a QEMU issue.  There could be a difference in
Binutils version but I don't think a Binutils difference can cause fenv
failure...

BTW could you (or Yinyu) push the patch?  I don't have a write access of
glibc.git (yet).
