`clippy-driver +stage1` doesn't work: `error while loading shared libraries: librustc_driver-2731d3486cc92946.so`

[ComputerDruid]

I tried this code:

$ ./x.py build --stage=1 clippy
$ rustup toolchain link stage1 build/host/stage1
$ clippy-driver +stage1 --version

I expected to see this happen: working clippy built from the same source as my stage1 rustc

Instead, this happened:

/usr/local/google/home/computerdruid/.rustup/toolchains/stage1/bin/clippy-driver: error while loading shared libraries: librustc_driver-2731d3486cc92946.so: cannot open shared object file: No such file or directory

this is basically the same problem as #78717 (cc #92538). i don't think there's an open issue specifically for running the tool directly so I'll keep this one open in the meantime.
