Committed, thanks!

I made a couple modifications to the port. xvid and a52
compilation were nonfunctional, and the post-configure target
is unnecessary.

Many users will get an error upon link. Recompiling/reinstalling
mjpegtools will fix this. Depending on the frequency of people
complaining about this, it may be necessary to add a disclaimer
to the build process.

I'm a bit confused about the email in this PR about stdint.h.
That library is no longer included in avidemux/ADM_h263/ADM_mp4.cpp.
*shrug*
