These changes make library lookups more robust. The core change is that
library lookups now first look a set of predefined locations before checking
the ldcache. This also handles cases where an ldcache is not available more
gracefully.

This change adds a Locator that can be used to locate libraries.
If library names are specified, the ldcache is searched otherwise
symlinks are resolved.
