Bug#977941: gmerlin FTCBFS: uses AC_TRY_RUN for posix semaphore check

Tue Dec 22 11:43:05 GMT 2020

Source: gmerlin
Version: 1.2.0~dfsg+1-6.1

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.
