I have found a workaround for the issue by compiling alsa-lib static. It
seems like the references to the variables are not set when aplay is
dynamicly linked with alsa-lib.

Actually not sure if it's either the GCC compiler which does something
wrong, a bad parameter while configuring or something in the code that
causes this.
