Miguel Ojeda c8cbe2fc22 rust: kbuild: remove --remap-path-prefix workarounds ... Commit 8cf5b3f836 ("Revert "kbuild, rust: use -fremap-path-prefix to make paths relative"") removed `--remap-path-prefix` from the build system, so the workarounds are not needed anymore. Thus remove them. Note that the flag has landed again in parallel in this cycle in commit dda135077e ("rust: build: remap path to avoid absolute path"), together with `--remap-path-scope=macro` [1]. However, they are gated on `rustc-option-yn, --remap-path-scope=macro`, which means they are both only passed starting with Rust 1.95.0 [2]: `--remap-path-scope` is only stable in Rust 1.95, so use `rustc-option` to detect its presence. This feature has been available as `-Zremap-path-scope` for all versions that we support; however due to bugs in the Rust compiler, it does not work reliably until 1.94. I opted to not enable it for 1.94 as it's just a single version that we missed. In turn, that means the workarounds removed here should not be needed again (even with the flag added again above), since: - `rustdoc` now recognizes the `--remap-path-prefix` flag since Rust 1.81.0 [3] (even if it is still an unstable feature [4]). - The Internal Compiler Error [5] that the comment mentions was fixed in Rust 1.87.0 [6]. We tested that was the case in a previous version of this series by making the workaround conditional [7][8]. ...which are both older versions than Rust 1.95.0. We will still need to skip `--remap-path-scope` for `rustdoc` though, since `rustdoc` does not support that one yet [4].
