A recent commit in GLIBC [1] got rid of _LIB_VERSION, which
makes Perl's build fail:
| pp.c:47:5: error: unknown type name '_LIB_VERSION_TYPE'; did you mean '__VERSION__'?
|      _LIB_VERSION_TYPE _LIB_VERSION = _IEEE_;
|      ^~~~~~~~~~~~~~~~~
|      __VERSION__
| pp.c:47:38: error: '_IEEE_' undeclared here (not in a function); did you mean '_SIZET_'?
|      _LIB_VERSION_TYPE _LIB_VERSION = _IEEE_;
|                                       ^~~~~~
|                                       _SIZET_
| make[1]: *** [pp.o] Error 1

The current config.sh enables d_libm_lib_version for
everyone, with special cases left to undefine it as fixup
(such as MUSL [2]).

Since this may only affect some BSDs and Cygwin [3], it
follows that the opposite (defining it) should be a fixup
for those special cases.
