cmuses configure checks an absolute path for the existence of a kernel header. This results in a check against the hosts version of /usr/include/sys/soundcard.h, which potentially does not exists (at least on my system). This patch supersedes http://patchwork.openwrt.org/patch/2713/. Signed-off-by: Mathias Kresin <openwrt@kresin.me> SVN-Revision: 39417
