Adhemerval Zanella ecb1e7220d powerpc: Do not raise exception traps for fesetexcept/fesetexceptflag (BZ 30988) 
According to ISO C23 (7.6.4.4), fesetexcept is supposed to set
floating-point exception flags without raising a trap (unlike
feraiseexcept, which is supposed to raise a trap if feenableexcept was
called with the appropriate argument).

This is a side-effect of how we implement the GNU extension
feenableexcept, where feenableexcept/fesetenv/fesetmode/feupdateenv
might issue prctl (PR_SET_FPEXC, PR_FP_EXC_PRECISE) depending of the
argument.  And on PR_FP_EXC_PRECISE, setting a floating-point exception
flag triggers a trap.

To make the both functions follow the C23, fesetexcept and
fesetexceptflag now fail if the argument may trigger a trap.

The math tests now check for an value different than 0, instead
of bail out as unsupported for EXCEPTION_SET_FORCES_TRAP.

Checked on powerpc64le-linux-gnu.
