backports: suppress errors from 'make kernelversion'v5.10.42-1
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 was fixed upstream in commit 805b2e1d427a ("kbuild: include
Makefile.compiler only when compiler is needed").
To work around it, pass M= as suggested here:
