libgcc_s.so produced by llvm-runtimes/libgcc contains a reference to __getauxval on aarch64, which should be defined by libc.
But musl doesn't expose it.
There is a MR for that (https://www.openwall.com/lists/musl/2023/10/12/3), but haven't merged yet.
With that patch applied to musl-1.2.5, libgcc works well on aarch64.

Hitting the same issue. @mojyack: Mind making a PR which applies the patch to musl?

To Gentoo? Okay I'll do that.  
Should we also report this to the upstream ML?

A release is hopefully upcoming soon. I recommend replying to that ML post and pinging it. Maybe try on IRC too.
Comment 4 mojyack 2025-05-30 02:18:39 UTC 
I sent a message to the ML.  
Maybe waiting for moderator approval.
