        src/tests/lib/libc/gen: t_fpclassify.c

Log Message:
t_fpclassify: Fix build properly without __HAVE_LONG_DOUBLE.

Centralize use of union ieee_ext_u, used on machines where double is
not the same as long double, so most of the long double code doesn't
need __HAVE_LONG_DOUBLE conditionals (reminder: __HAVE_LONG_DOUBLE
means long double is _larger_ than double, not just that long double
exists; long double always exists and should work either way).
