There are 2 different things:
1. put git describe output into some header file
2. make things to rebuild with every new commit

So I actually stuck at solving 2, because 1 is trivial. My original solution for 2 was to "depend" on refs/heads/*. This worked besides git gc, but had a lot of troubles with worktrees. And this time I switched to the "touch tmpfile" trick with the date taken from git log. This requires .LOW_RESOLUTION_TIME in makefile, so probably not the best solution again, but should hopefully be more future-proof than the previous one.
