18     # 2.0.51, we now have support for installing libraries to lib32/lib64
19     # to accomidate the needs of multilib systems. It's no longer a good idea
20     # to assume all libraries will end up in lib. Replace any (sane) instances
21     # where lib is named directly with $(get_libdir) if possible.
