dev-lang/rust: Fix build with musl 1.2.4

[vimproved]

Rust 1.72.0 bumped the version of the libc crate required by the std to 0.2.146, which finally means that the stdlib no longer references LFS64 symbols. This commit make rust 1.72.0 bootstrap from 1.72.0, and adds a patch that bumps all remaining dependencies on libc <0.2.146 in vendored crates.

Pinging @xen0n since he's been doing a lot of rust work while gyakovlev is away.

@vimproved You might want to link this to the Gentoo issue. https://bugs.gentoo.org/903607

Any clue what's going on with the CI? pkgcheck isn't giving me anything...

ConflictingChksums	distfile 'rust-1.72.0-arm-unknown-linux-gnueabihf.tar.xz' has different checksums (blake2b, sha512, size) for package: dev-lang/rust

I ran into it when applying your fix locally, my workaround was to remove rust-1.72.0-arm-unknown-linux-gnueabihf.tar.xz* from /var/cache/distfiles and the corresponding lines from the Manifest file, then regenerated the Manifest with pkgdev manifest.

I have also run into similar in the past with older rust versions for other bootstrap tarballs, maybe upstream is modifying these files after release?

Must have only partially downloaded. I think I fixed it.

Any progress on this PR? I'm running into these build issues in the musl+clang system profile.

This has been ready on my end for a while, although it appears that it needs to be rebased.

Ah, I've never noticed before that this only touches dev-lang/rust and nothing else. Should be good to go (we can always fix later should anything go wrong), sorry for the long delay!
