Subject: [PATCH] kbuild: do not overwrite .gitignore in output directory
Commit 3a51ff344204 ("kbuild: gitignore output directory") seemed to
bother people who version-control output directories.
Andre Przywara says:
"Unfortunately this breaks my setup, because I keep a totally separate
git repository in my build directories to track (various versions of)
.config. So .gitignore there is carefully crafted to ignore most build
artefacts, but not .config, for instance."
