Is this compilation using buildroot? We have had many people with
bugreports that turned out to be gcc CSE bug which is not patched in
buildroot. And the fact the build root doesnt seem to install the config
files for alsa-lib.

For testing here we always use images generated by OpenEmbedded
www.openembedded.org. So that gets better ALSA support for ASoC stuff
anyway :-)
