GCC toolchain glibc-linked binaries with musl libraries and headers, including musl dynamic loader

Out of the glibc tarpit

> glibc-linked binaries with musl libraries

Why have any glibc? GCC et al. work fine compiled against musl (as proven by ex. Alpine only doing musl). Or is it for running on GNU/Linux systems (can't you statically link the build chain?)?

Maybe they want dns resolution to work properly

Are you talking about the TCP fallback that musl has also had for 2 years? https://www.openwall.com/lists/musl/2023/05/02/1

In any event, that makes no sense. Pretend for a moment that glibc has working DNS and musl doesn't have working DNS (not true, but let's pretend). You don't build your compiler chain with working DNS support and then use it to build programs without working DNS.

Does a compiler need to resolve DNS?

What's different from https://toolchains.bootlin.com/ ?

Or using Zig?

Does this mean useful interfaces like PAM and nsswitch work on musl now?

PAM has worked on musl for many years. musl-nscd has provided nsswitch functionality for about a decade now.
