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

Log Message:
t_fpclassify: Revert previous -- __HAVE_LONG_DOUBLE is used wrongly.

__HAVE_LONG_DOUBLE being defined means long double is _different_
from double (typically 80-bit or 128-bit extended precision), and not
being defined means long double is the same as double.

Any code that uses ordinary long double arithmetic or long double
libm functions should work with or __HAVE_LONG_DOUBLE.

But without __HAVE_LONG_DOUBLE, we don't have things like union
ieee_ext_u for breaking apart the internal representation.

Will re-fix the build in a subsequent change coming up momentarily.
