Yeah, I think that fix is back from a time when cargo was worse at dealing with multiple crates. @bors r+ |

Fix compile-test from forcing a rebuild. If the `compile-test` test was run, then running a cargo build command immediately after caused everything to be rebuilt. This is because the `compile-test` test was deleting all `.rmeta` files in the target directory. Cargo recently switched to always generating `.rmeta` files (rust-lang/cargo#6883), and when the files are deleted, it thinks it needs to be rebuilt. I am not very familiar with compiletest or clippy, so please take a close look and test this out (with the most recent nightly). In particular, make sure it doesn't revert the fixes from #3380 (it seems to work for me). Also @oli-obk mentioned something related in rust-lang/rust#60190 (comment), and I want to make sure that is addressed as well. Fixes #4114
