musl upstream has a FAQ entry specifically for this error:
https://wiki.musl-libc.org/faq.html#Q:-Why-am-I-getting-

Suggested workarounds are in the FAQ.

The first attempt to tinderbox a musl image failed at all.

I'll mass close therefore all filed bug reports of the last days related to this tinderbox image.

Please feel free to re-open if you think that the bug is real in musl and not fixed by the musl overlay.
