Since kernel 5.8, specifically commit 4d0831e8a029 ("kconfig: unify
cc-option and as-option"), 'make kernelversion' will call into the
Kconfig system, evaluating cc-option from scripts/Kconfig.include,
which requires a writable current working directory due to the use
of ".tmp_<pid>" for temporary files. This seems questionable, but
since the kernelversion really isn't affected, we can ignore it.

I also mentioned this upstream, see the thread after the commit:
