Instead, pull in r371324 from upstream libc++ trunk (by me):
Remove ::gets for FreeBSD 13 and later
Summary:
In https://svnweb.freebsd.org/changeset/base/351659 @emaste removed
gets() from FreeBSD 13's libc, and our copies of libc++ and
libstdc++. In that change, the declarations were simply deleted, but
I would like to propose this conditional test instead.
