[openal] Releasing openal-soft with linux games

[Mark Sibly]

Thanks for the tips everyone!

I've installed the latest ubuntu on a brand new/cheap machine, and
everything works really well! Audio (and openal) worked first time without
a hitch (wow) and seems to be lag-free etc, so IMO there's no issue. But
I'm not the customer etc...

I got RPATH=$ORIGIN going, but this effectively forces the app to use the
openal-soft that ships with the app. I think I prefer the app to 'default'
to using system openal - which I reckon will work in 99% of cases - but to
perhaps also provide a secondary/panic batch file that mungs
LD_LIBRARY_PATH to use an internal version of openal-soft. Or maybe this
isn't even really necessary these days?

Another quicky: How can I tell whether the system openal is in fact
openal-soft? And if so, which version?
