Summary: missing libs in link command of chan_h323.so: module
fails to load
Description:
It used to be that when building with chan_h323 enabled, asterisk would
fail the build after generating channels/h323/Makefile.ast . Now it
doesn't. However values from it don't seem to be used when linking
channels/chan_h323.so .

If I try to load that module it would fail, due to missing symbols that
appear to come from openh323.
Now let's rebuild:
$ rm channels/chan_h323.so
$ make NOISY_BUILD=1

That looks more like bad old chan_h323.
Now, rebuild, but also remove channels/h323/Makefile.ast:
$ rm channels/chan_h323.so channels/h323/Makefile.ast
$ make NOISY_BUILD=1
...
make[1]: Entering directory
`/home/tzafrir/Proj/Asterisk/Git/asterisk/channels'

$ ls channels/h323/Makefile.ast
ls: cannot access channels/h323/Makefile.ast: No such file or directory
As a temporary workaround, I included a simple patch to the main makefile
to allow me to cleanly generate channels/h323/Makefile.ast
