Problem is sysv version of fpu-target.h has been selected because configure
found fpsetmask but it didn't find fp_except or fp_rnd because they are
defined in <math.h>, not <ieeefp.h>.  The fp routines are also declared
in <math.h>.

On hpux11, this doesn't happen because fpsetmask is gone.  As a result,
generic support is selected. This is probably not optimal but
that's another issue.
