The plus comes from the fact that your kernel directory is not clean!

This (upstream) kernel helper scripts adds it:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/setlocalversion#n165

The solution is not to tinker around with the script but:
1) build as Fabian directed you, i.e., a single clone plus make - no tinkering
2) if you add changes on top, do so in a clean way.

I can just setup a clean Debian install the build dependencies and build just
fine.
