OS is Gentoo (musl libc) and I have tried with both gradlew and Gradle 8.12 bin package.

Please put additional context inside of your first post. Like this it’s hard to follow and as you see now. You already have 2 different discussions with the same proposals.

Sorry, not used to Slack so I didn't think it would turn all my messages into threads.

musl isn't supported but it should still continue (just without integration), perhaps something else broke https://github.com/gradle/native-platform/pull/284

Downgrading to v8.11.1 fixed it, so it must have broken somewhere between it and the v8.12 release. I would try to bisect it down to the commit, but I can't get any version after 8.10 to build. I get this error:
