Bring make dist in sync with autogen.sh's retrieval of ffmpeg
checkout, which also includes an update to selected revision
of libswscale external. Also include *.S files (needed for
e.g. ARM build).
Original commit message from CVS:
* Makefile.am:
Add gst-libs to DIST_SUBDIRS to make sure that it's always
disted.
* autogen.sh:
Remove -I m4 from autogen.sh, it's not disted and used anymore and
thus makes autogen.sh fail if run on a tarball. Fixes bug #563305.

* autogen.sh:
* ffmpegrev (FFMPEG_EXTERNALS_UPDATE): Because ffmpeg checks out
libswscale via an svn:externals, checking out an old ffmpeg does
not check out a corresponding libswscale. Keep the swscale
checkout manually synchronized, then. Update this when you update
FFMPEG_REVISION.
Original commit message from CVS:
* autogen.sh:
Add -Wno-portability to the automake parameters to stop warnings
about GNU make extensions being used. We require GNU make in almost
every Makefile anyway.
* configure.ac:
Use AM_PROG_CC_C_O as a compiler that accepts both -c and -o
at the same time is required for per target flags.
Original commit message from CVS:
* autogen.sh: execute ffmpeg's autogen.sh directly
* gst-libs/ext/ffmpeg/autogen.sh: Add a #! line. Specify bash,
since there are bashisms ('local').
