[pulseaudio-discuss] Build assembler errors on ARM OMAP3

[Kurt Taylor]

Thanks for your help Arun. I was finally able to come back to this problem.
Here is the last lines of a make on a clean git clone showing the errors on
the beagleboard (linaro ALIP).

Adding "ite" before the addcs did not build, adding itt built and ran, but
unloaded alsa module.
