Subject: [PATCH] avserver: Remove unused loadable module support
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

There is no record of this ever being used at all, anywhere,
since the feature was added in 2effd274466.

This gets rid of extra linker tricks just to support a feature
that isn't used, simplifying portability to other platforms.
