Caused by the following change in musl: https://git.musl-libc.org/cgit/musl/commit?id=98e688a9da5e7b2925dda17a2d6820dddf1fb287

Reproduction Steps

1. Setup Alpine Edge environment with musl 1.2.3.
2. Attempt a build

Expected behavior

Build should pass, as with musl 1.2.2

Actual behavior

Failure, as described in description.

Regression?

No response

Known Workarounds

Removing the problematic commit from musl does the trick.

Configuration

Alpine Edge Musl 1.2.3 installer version 6.0.102 with runtime 6.0.2 (as problematic files havn’t changed between 6.0.2 and 6.0.3, this issue should exist with current version)
