I don't think mismatching TLS/non-TLS Mesa and X server works, but I
don't think that's a combination anyone cares to support (or is
possible to support?).

The X server isn't required to compile Mesa, so it doesn't make sense
to try to check if the X server supports TLS. I think the idea is, if
the system supports TLS, let's default to enabled for both Mesa and
the X server, and if you do something else and it breaks then you get
to keep the pieces.
