No, it wouldn't. It doesn't address the manjority of my concerns.

The native recipes shouldn't depend on the SDK gcc version either.

I don't believe that is the issue. I don't have "nativesdk-mgen", but
taking nativesdk-sed as an example:
$ bitbake nativesdk-sed -S none
(to dump the signatures for that recipe)
$ bitbake-dumpsig
tmp/stamps/aarch64-nativesdk-pokysdk-linux/nativesdk-sed/4.8-r0.do_prepare_recipe_sysroot.sigdata.*
shows:

amongst other things.
i.e. the nativesdk recipes *clearly* do have a dependency on the gcc
version used for nativesdk.
Cheers,
