On macOS 14, a guard in <math.h> changed:

Therefore the darwin_flt_eval_method fixincludes fix doesn't match any
longer, leading to a large number of testsuite failures like
/private/var/gcc/regression/master/14-gcc/build/gcc/include-fixed/math.h:69:5:
error: #error "Unsupported value of __FLT_EVAL_METHOD__."
where __FLT_EVAL_METHOD__ = 16.
This patch adjusts the fix to allow for both forms.
Tested with make check in fixincludes on x86_64-apple-darwin23.0.0 and
verifying that <math.h> has indeed been fixed as expected.
