If the compiler is built with rpath = false, then it won't find its
own libraries unless the library search path is set. We already do that
while running the actual compiletests, but #100260 added another rustc
command for getting the target cfg.

Check compiletest suite=codegen mode=codegen (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu)
thread 'main' panicked at 'error: failed to get cfg info from "[...]/build/x86_64-unknown-linux-gnu/stage1/bin/rustc"
--- stdout

--- stderr
[...]/build/x86_64-unknown-linux-gnu/stage1/bin/rustc: error while loading shared libraries: librustc_driver-a2a76dc626cd02d2.so: cannot open shared object file: No such file or directory
', src/tools/compiletest/src/common.rs:476:13

Now the library path is set here as well, so it works without rpath.

@cuviper I know you're a busy man, but do you think its possible for you to give a brief example on how to test if my rustc binary is affected by this?

It seems to me that you were unable to compile/bootstrap your rustc binary on x86_64-unknown-linux-gnu, however I did not have any problems with bootstraping mine on armv7a-unknown-linux-musleabihf, despite using rpath = false in my config.toml - so I'm slightly confused here if I should backport your patch into my patchset?

This only affects the in-tree testsuite, like ./x.py test ui, as our compiletest runner was trying to invoke rustc without the path to its libraries.

Once you've built the toolchain and installed it somewhere, it's up to you to make sure that your library path is correct. This hasn't changed.
