Hi,
This patchlet adds a check to configure that makes sure that we have a
working alsa setup.
Previously, if --enable-alsa was given but the user forgot to install
the alsa libs proper, the build failed later on due to eventually
missing libs. The patch makes sure that the user can spot that alsa
support was turned off after configuration completed.
thanks,
