    perl: Undefine d_libm_lib_version.
    
    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.
