[pulseaudio-discuss] Build assembler errors on ARM OMAP3

[Kurt Taylor]

I submitted a ticket and patch that fixes these build errors - tested on a
Beagleboard (OMAP3) with Linaro ARM Linux image. I did not test on other
platforms due to this being specific to ARM.

Thanks again for your help Arun!
