Latest rustup update version breaks compilation

[delehef]

Describe the bug

Running a fresh rustup install nightly && cargo build fails, the core message being:

note: Could not start dynamically linked executable: /home/[xxx]/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-unknown-linux-gnu/bin/gcc-ld/ld.lld
          NixOS cannot run dynamically linked executables intended for generic
          linux environments out of the box. For more information, see:
          https://nix.dev/permalink/stub-ld
          collect2: error: ld returned 127 exit status

Steps To Reproduce

Steps to reproduce the behavior:

1. have a rust project
2. rustup install nightly (or rustup update if you already have one)
3. cargo build

Expected behavior

Either the rustup gcc/ld to be patched for NixOS use, or rust to use the system gcc/ld.

Actually, it looks like this is an issue specifically appearing with nightly-2024-05-18-x86_64-unknown-linux-gnu; so I'll try to pass the message upstream.

[delehef]

Very specifically, this is the commit introducing the issue, when it has been decided to switch from the system linker to ldd.

I suppose the new [toolchain]/lib/rustlib/x86_64-unknown-linux-gnu/bin/gcc-ld/ binaries should also be elf-patched?

[Nemo157]

Patching those binaries will make them execute, but they also need the ld-wrapper applied so that the binaries they build will also get patched automatically.
