Try: rustup target add aarch64-gentoo-linux-musl rustlib installed by the build is nick named "aarch64-unknown-linux-musl", so the config is in a way right that the std is missing. But working dev-lang/rust-bin does install the very same rust-std "aarch64-unknown-linux-musl" current workaround is therefore to use dev-lang/rust-bin instead.

P.S: firefox will most likely also be affected, but I chose spidermonkey as it has less dependencies to bootstrap through, hope its okay.

I really think we should just apply the musl/Rust patch conditionally for now.
the detection seems to work as expected if rust-bin is used on amd64-musl and aarch64-musl. maybe you want to talk to anarchy, I think it was him who wrote both the rust musl patch and those patches adressing musl issues included into the firefox patch tarball.

I'm talking about glibc here though.
