Hello,
I got following idea.
If different branches seriously differ and you switch branches, then
it's more likely you will loose most part of build files (e.g. when
run build).
Also in projects that may have some bugs in build system (e.g. buggy
makefiles) there is a chance you will not get clean build environment.
E.g. somebody forgot to add include file as dependency in Makefile ---
oops, you're in trouble.
Even without bugs in build system, some temp files are overwritten
each time you run build for a custom branch.
I think using overlays for other files can help much to solve this
issue. You can have git repository in regular directory (like now) and
overlay fs mounted over this repository (for each branch its own
overlay).
Another benefit is clearing source tree after build.
What do you think, guys? If it sounds good, I could work on this,
maybe even on my work.

Use ccache.

Fix your Makefiles. Or run git clean, see below.

git clean -dfx.
Or use two different working trees. See contrib/workdir/git-new-workdir.

Thank you Tom, that's what I wanted.
