Thread-local storage in GCC is platform-specific, and some platforms that
are otherwise perfectly capable of running mpv may lack TLS support in GCC.
This change adds a test for GCC variant of TLS and relies on its result
instead of assumption.
Provided that LLVM's `__thread` support is similar to GCC, the test is
called "GCC/LLVM TLS".

Mktemp on BSDs (at least on OpenBSD) don't have "--tmpdir" option.
Set temporary directory to /tmp by default. Use of ${TMPDIR:=/tmp} allows
overriding temporary directory via environment if needed. (And is indeed needed
in OpenBSD ports infrastructure.)

The code actually uses blocking mode, so opening sound device in non-blocking
mode results in choppy sound. Also, inflating the buffer isn't necessary in
blocking mode, so the function may simply return without doing anything.
