An alternate link strategy for languages which need to package native deps up as shared libraries, which only links native nodes which have an explicit edge from non-native code as separate, and statically linking all other native nodes into a single giant shared library. This reduces the number of shared libraries considerably and also allows the linker to throw away a lot of unused object files.

Parameters:

cellPathResolver -

nativeLinkTargetRoots - root nodes which will be included in the omnibus link.

nativeLinkableRoots - root nodes which are to be excluded from the omnibus link.

Returns:

a map of shared library names to their containing SourcePaths.
