Subject: Update for dynamic loading of ALSA

I sent you a patch a few months ago which enables SDL to load ALSA
dynamically. Now I've finally got time to tweak this yet some more. I've
added code from alsa.m4 (from alsa's dev package) to acinclude.m4, and
made the detection of the alsa library name a bit better. I've also
fixed up the loading versioned symbols with dlvsym, so that it falls
back to dlsym.

I wouldn't say the configure script is complete yet, but this is how far
I've come this time, and I'm no expert at those things.
