build: recompile txr.c if build_id changes.
With this change, it is possible to
make build_id=abcd
to rebuild TXR with the given build ID. Any changes in the
value of a dynamic, git-generated build_id will likewise
trigger a rebuild.
* Makefile (old_build_id): New variable. We read the old build
ID from a file called .build_id in the build directory. If
it differs from the current expanded ID, build_id_exp,
we remove the object files affected by build_id.
In all cases, we then write the current build ID into the
.build_id file.
(clean, distclean): Remove .build_id.
