I see a similar logic in
recipes-kernel/linux/setup-defconfig.inc as well.

Considering similar problem

https://lore.kernel.org/all/20220413155249.3458236-2-raj.k...@gmail.com/

was wondering as to what might be a better way to solve this?

There is also git rev-parse HEAD instances in oe-core as well and
bitbake(lib/layerindexlib/cooker.py) as well.

I wonder since we know cwd=p, could we use that to set
https://git-scm.com/docs/git/2.35.2#Documentation/git.txt-codeGITCEILINGDIRECTORIEScode
 (which if my understanding is right, came in around v1.5.5.1-319-g0454dd93bfb2)

OR maybe just set it to the base conf similar to what was done on
master oe-core/meta/conf/bitbake.conf (commit
02ecf3e2a98a614805f6f2574c2bf14162192d01 "bitbake.conf: Prevent git from
detecting parent repo in recipe")?

I am not sure if we should considering just side stepping this issue via
just not using the git to get the version string.. just my 2 cents.
