Szabolcs Nagy 0af3095468 [PR libgfortran/78314] Fix ieee_support_halting
ieee_support_halting only checked the availability of status
flags, not trapping support.  On some targets the later can
only be checked at runtime: feenableexcept reports if
enabling traps failed.

So check trapping support by enabling/disabling it.

Updated the test that enabled trapping to check if it is
supported.
