Panic while compiling

[John Klos <john%ziaspace.com@localhost>]

Hi,

I've been playing with running riscv64 in qemu - so far, it has been a 
very clean and easy experience. Thanks!

I decided to start a bulk package build, and things were running quite a 
bit faster than I'd imagine that an emulation rightly should (although 
distcc certainly helps). However, it paniced while compiling lang/llvm :(

This is using current built from late 28-May-2023 sources.

Anything I should try, or any data I should collect and share?

Thanks,
John Klos
