Log:
configure: If cross-compiling, assume we have working semaphores

The Asterisk 13 configure.ac checks for HAS_WORKING_SEMAPHORE but does not have
an option for cross-compiling so it fails with an exit. Since we're cross-
compiling, we can't exactly go looking for the header. The semaphore.h header
is relatively common:
* It's part of the POSIX standard
* It's part of GNU C Library
As such, we assume that it will be present when cross-compiling.

As such, this patch defaults "HAS_WORKING_SEMAPHORE" to "1" if cross-compiling
is detected.

If you're cross-compiling to a platform that doesn't support this, then make
sure you re-define this to 0.
