This should be investigated (since it should be possible), but disabling it for
now seems better than having a significant percentage of pkgsMusl broken.

For static variant this might not be needed (pkgsStatic.python3 built for me before this change), but maybe that doesn't matter.

[SuperSandro2000]

Would this exclude clang by accident?

[sternenseemann]

No, what would clang have to do with that?

I believe this was due to an issue with our cc/bintools wrappers' argument parsing for PIE hardening. It only shows up for musl, because that's currently the only package set where PIE hardening is enabled by default. I will attempt to revert this along with the fix in #135619.
