Availability of `ptsname_r` is not checked at runtime on macOS #123797

Bug report

Bug description:

Use of this was recently added in Python 3.13 but it is only available in macOS 10.13.4+ and there is not a proper runtime check for availability. This means that in python-build-standalone we need to ban the symbol instead of allowing proper weak linking.

See discussion at https://github.com/indygreg/python-build-standalone/pull/319#discussion_r1747174338
