New comment by klarasm on void-packages repository https://github.com/void-linux/void-packages/pull/40414#issuecomment-1309355929 Comment: That did it. After running `./xbps-src zap` and rebootstrapping it builds fine on x86_64-musl without `musl-devel`. I must have had something polluting the masterdir. Will run a few more tests, and if nothing else turns up I'll update this PR to version 1 instead.
