Branch: MAIN
Import patch from Debian http://bugs.debian.org/347650 which hacks around libtool deplib re-ordering, which inhibits -Wl,--as-needed. You have to set -Wl,--as-needed seperately in LDFLAGS for this to do any good, -Wl,--as-needed,--something-else will not do, but you can set -Wl,--something-else afterwards. Also make sure eclasses I 'own' run elibtoolize so they can reap the benefit.
