New debugedit support for FEATURES=splitdebug, by Sven Wegener:

This will create new-style buildid symlinks for the splitted debuginfo and also
a symlink to the binary that belongs to the debuginfo. Requires debugedit from
rpm 5. Old versions of debugedit ignore all unkown command line arguments, so
this is a no-op for them.

New debugedit tarball: http://dev.gentoo.org/~swegener/distfiles/debugedit-5.0.0.tar.bz2
