gegl fails build-time tests on ia64. From the log and the content of
the script, it looks as though examples/frame-counter (source code:
examples/frame-counter.c) is segfaulting whenever it was run with
"--video-codec mpeg4" (but not for 512kb-28fps.ogv).

This might actually be a bug in libavcodec (ffmpeg), which gegl seems
to use to process these videos. A newer version of ffmpeg also fails
its own build-time tests on ia64.
