Currently a dummy rust code is compiled to detect if the rust feature
could be enabled. It turns out that in this case rust emits a dependency
file without any external references:
/perf/feature/test-rust.d: test-rust.rs
/perf/feature/test-rust.bin: test-rust.rs
test-rust.rs:
This can lead to a situation, when rustc was removed after a successful build,
but the build process still thinks it's there and the feature is enabled on
subsequent runs.
Instead simply check the compiler presence to detect the feature, as
suggested by Arnaldo.
This way no actual test-rust.bin will be created, meaning the feature
check will not be cached and always performed. That's exactly what we
want, and the overhead of doing this every time is minimal.
Tested with multiple rounds of install/remove of the rust package.
