Original commit message from CVS:
2008-02-23  Bastien Nocera  <hadess@hadess.net>

* configure.ac: Add checks for Flex/Yacc/Bison and other
furry animals, for the new goom 2k4 based plugin

* gst/goom/*: Update to use goom 2k4, uses liboil to detect
CPU optimisations (not working yet), move the old plugin to...

* gst/goom2k1/*: ... here, in case somebody is sick enough

Fixes #515073
