Just to throw in random ideas:
Let libtool output Makefile snippets in .libs/Makefile.libdep at link
time, providing dependency information based on what it knows then.
`make' is the canonical program to deal with topological sorting.

Let make use these at install time, maybe through a generated script or
some other mechanism (so that the Automake-generated Makefiles do not
have to depend on .libs/Makefile.libdep to exist).

No, I have not thought this through.
