Rollup merge of rust-lang#115968 - git-bruh:master, r=workingjubilee

Don't use LFS64 symbols on musl

Supersedes rust-lang#106246

~~Note to packagers: If your distro's musl package has already been updated, then you won't be able to build a newer version of rust until a new rust release is made with these changes merged (which can be used to bootstrap). I'm using a super hacky method to bypass this by creating a stub library with LFS64 symbols and building a patched rust, so the symbols satisfy the build requirements while the final compiler build has no references to LFS64 symbols, example: https://codeberg.org/kiss-community/repo/pulls/160/files~~ Doesn't seem to be necessary with new rustup nightly builds, likely due to updates to vendored crates
