gmerlin fails to cross build from source, because it uses AC_TRY_RUN
with no last argument nor cache variabel to check for posix semaphores.
In this case, degrading the check to AC_CHECK_FUNC for the cross case
seems reasonable. I'm attaching a patch that implements this.
Please consider applying the patch and close this bug when doing so even
though there are more cross compilation issues underneath.
