S390: Fp comparison are now raising FE_INVALID with gcc 10. 

The s390 gcc bug https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77918
"S390: Floating point comparisons don't raise invalid for unordered operands."
is fixed with gcc 10. Thus we conditionally set FIX_COMPARE_INVALID
to 0 or 1.

There exists an equivalent gcc bugzilla for Intel:
<https://gcc.gnu.org/bugzilla/show_bug.cgi?id=52451>.
Once the s390 gcc bug is fixed, the definition of FIX_COMPARE_INVALID
should have a __GNUC_PREREQ conditional added so that e.g. the workaround
to call feraiseexcept (FE_INVALID) in math/s_iseqsig_template.c can be
avoided. */
#define FIX_COMPARE_INVALID 1

# define FIX_COMPARE_INVALID 0
