Oracle Linux, follows the same test and workaround done in

ext/POSIX/t/math.t: don't assume the sign of NaN
The test in Configure warns:
/* Note that whether the sign bit is on or off
* for NaN depends on the CPU/FPU, and possibly
* can be affected by the build toolchain.
but this test assumed that the default NaN was always positive,
but this isn't the case with the Sun/Oracle workshop cc, whether
on Oracle Linux or on Solaris.
copysign() is however well defined for NaN, so we can modify the
sign on NaN and test that with signbit().
Fixes #21533

POSIX: MSVC really does have copysign
This is enabled in config.gc, and gcc builds were using only msvcrt
for a long time, so presumably MSVC 2013 which uses msvcrt also
supports it. Later MSVC uses ucrt which definitely supports
copysign.

Log Message:
-----------
POSIX: MSVC really does have signbit()
But it appears that the fallback for Perl_signbit() in numeric.c
is broken when we've found a definition for Perl_fp_class_nzero().
When Perl_fp_class_nzero is defined, the fallback Perl_signbit()
simply returns that value, but Perl_fp_class_nzero() only returns
true when the number is negative zero, not for any negative number.
But C99 requires signbit(), so I don't think it's worth spending
any more time looking into this. We might want to eliminate
Perl_signbit() from numeric.c, or try to fix it.

Log Message:
-----------
POSIX: MSVC defines all of these
It also defines fpclassify(), but that's a more complex change
due to the classification macros in perl.h
