meson: Update the pthread feature checks

Browse Source 
For GNU extensions, we need to define _GNU_SOURCE; but, more
importantly, we need to tell Meson to use the threadlib dependency when
compiling and linking the feature check.

This currently exposes a bug in Meson; see:

https://github.com/mesonbuild/meson/issues/2165

But once that's fixed, the check will work as intended.
