[Mingw-cross-env-list] OpenAL

[Martin Gerhardy]

Another attempt to get openal into mingw-cross-env

I've changed the way cmake is called (according to the docu) and also
try to link the included test program (comes with openal). the linking
fails with undefined references - if someone has any ideas about this i
would be very glad 

(this is the last package that is needed on my side to get my project
cross-compiled with mingw-cross-env btw ;))

Greetings
Martin
