[PATCH 1/5] configure: Require openal-soft at build-time for xaudio2

[Andrew Eikum]

We depend on various openal-soft symbols to build, and we require
openal-soft for basic functionality anyway, so just require it at
build-time.

We still avoid depending on it to load the module, and instead check for
the extension's presence at run-time.

Should fix bug 39165.
