| # to accomidate the needs of multilib systems. It's no longer a good idea |
| # to assume all libraries will end up in lib. Replace any (sane) instances |
| # where lib is named directly with $(get_libdir) if possible. |
| # |
| # Jeremy Huddleston <eradicator@gentoo.org> (23 Dec 2004): |
| # Added support for ${ABI} and ${DEFAULT_ABI}. If they're both not set, |
