Dimitry Andric 41e7283b76 Refine check for _LIBCPP_C_HAS_NO_GETS on FreeBSD 
Summary:
In D67316 we added `_LIBCPP_C_HAS_NO_GETS` to signal that the C library
does not provide `gets()`, and added a test for FreeBSD 13 or higher,
using the compiler-defined `__FreeBSD__` macro.

Unfortunately this did not work that well for FreeBSD's own CI process,
since the gcc compilers used for some architectures define `__FreeBSD__`
to match the build host, not the target.

Instead, we should use the `__FreeBSD_version` macro from the userland
header `<osreldate.h>`, which is more fine-grained.  See also
<https://reviews.freebsd.org/D22034>.

libc++ Documentation
====================

The libc++ documentation is written using the Sphinx documentation generator. It is
currently tested with Sphinx 1.1.3.

To build the documents into html configure libc++ with the following cmake options:

  * -DLLVM_ENABLE_SPHINX=ON
  * -DLIBCXX_INCLUDE_DOCS=ON

After configuring libc++ with these options the make rule `docs-libcxx-html`
should be available.
