wrong variable used - caused the bottom field to be cut at the top
and random noise appear at the bottom. Patch from lucabon at infinito dot it.

Bump up the mplex version to 2.2.4 to reflect the minor changes/fixes made

Bug Tracker: [ 1265301 ] makefile.cfg should get more values from configure

Summary:
makefile.cfg should get more values from configure
the current makefile.cfg hardcodes many values (like
bindir and libdir) ... be nice if it accepted the input
values from the configure script :)

Add OS/X to the list of systems known to work.

Miissing '('

Not having soundcard.h but giving a "illegal ... IRIX" message was misleading.
Issue a better message ("unsupported audio system").

Hasn't built/installed in eons on Irix so remove mention of it.

More hardcoded '2's instead of using 'channels'.

Oops - hardwired 2 used in one place for the number of channels. Use 'channels'
like was done elsewhere (so that mono works ;))
