rust-src component is not self-contained anymore #74506
Description
Since #73441 I'm getting a failure while building libstd.
error: couldn't read /home/oliver/.rustup/toolchains/miri/lib/rustlib/src/rust/src/libstd/../backtrace/src/lib.rs: No such file or directory (os error 2)
--> /home/oliver/.rustup/toolchains/miri/lib/rustlib/src/rust/src/libstd/lib.rs:519:1
|
519 | mod backtrace_rs;
| ^^^^^^^^^^^^^^^^^
error: aborting due to previous error
Should we copy the backtrace folder into the rust-src rustup component or is there a better solution?
