Doesn't look like a bug in isnormal to me. That test is explicitly using
an IBM long double representation and can't possibly be expected to work
with IEEE long double - either it needs to be disabled for IEEE long
double, or to use -mabi=ibmlongdouble explicitly, or to use __ibm128 (but
if you use __ibm128 you can't then test the type-specific __builtin_isinfl
like it does at present).
