I was wondering about better incremental usage of 'revdep-rebuild --library', and would like to request that an age comparison be added.

I want to limit it to only files where the file being considered is OLDER than the library.

There are two places it could be done:
1. BUILD_TIME of the packages
2. mtime of ELF objects themselves.

This has two benefits:
1. Avoids rebuilding the same thing multiple times on two passes of revdep-build
2. Limiting the rebuild to only things that actually need it in a set.

This should be implemented in both the bash & python versions.
