Aegis solves this by calling a hook when the repository changes.

For tla, we could add a file which contain the timestamp of the latest
commit and its name to the {arch} directory.  Your makefile would
generate some source file based on that, and you could link it into your
application.

A similar trigger file for repository changes would be a nice thing to
have, too.

In-file revision IDs have been removed from the GCC tree due to constant
breakage in merges.
