  Let's first check the most likely cause. For fop_sqrt.tst, please
test commenting with // or /* */ the lines that have either $NaN
or $Inf.
  Also in the first suspect, clobber.tst might be failing at:
         jmpf(__LINE__, unord,       0, $(0.0 / 0.0))
but please test bisecting the tests, until finding the one that fails.
It must be calling abort, running in a debugger would be a bit
easier to debug.

  For call.tst, please also bisect to find what test is failing. This
test does extensive checking on to/from float/double tests, and
to/from float/double/word tests as well as several validations on
special values, for 32 bit, values like 0x80000000, 0xffffffff,
0x7fffffff, 0x80000001 and the similar 8 and 16 bit values, to
check for proper conversions.

  It must be something simple like the patch you just did, or
might be a qemu-user bug.
