So in case anyone wants to do some configure hacking..

This is broken.  We really should really use the host CC to build and 
run dyngen.  However, dyngen is disappearing soon so it's probably not 
worth fixing.

The audio driver probing is busted.  I usually use 
--audio-drv-list="sdl" FWIW but this shouldn't be necessary.  Right now, 
the audio driver code looks at the host platform and tries to guess the 
available audio drivers.  It would be better to just compile probe all 
of them.
