looks ok to me. since are are adding new architecture instead of just adding updated release I added few more people for comments.

I was wondering if we should fork the rid but it seems like we retro fit new architectures elsewhere to older releases as well.

In case it was not obvious, armv6 is only supported with mono runtime. From coreclr, we only build PAL, HP libunwind among few other pieces to support corehost (dotnet(1)) with -p:RuntimeFlavor=mono.

If this is working on Alpine Linux, I think would be nice to add a CI leg for linux-musl-armv6 in extra-platforms pipeline (it may need some extra work in our cross infra setup). If this is untested, I think we should skip armv6 for now.

Mono is currently broken on musl due to using libc symbols, but I'm in the process of fixing it for s390x and armv6.
