BUILD_LDFLAGS is primarily (but not exclusively) defined by bitbake.conf. Beside other things, it adds STAGING_LIBDIR_NATIVE and STAGING_BASE_LIBDIR_NATIVE as both rpath and rpath-link arguments to this variable.
Usually this shouldn't matter for class-target compilation, as it's normally expected to use only TARGET_* variables, not BUILD_* ones. This is not always the case with Rust - some crates are compiled for the host target even when the recipe target is class-target, e.g. for some compiler plugins, and I'm sure there are other reasons also. This makes some BUILD_* variables to be used in the this process, making the rpath variables from BUILD_LDFLAGS ending up in the final binary. >From the manpage of ld(1): "The difference between -rpath and -rpath-link is >that directories specified by -rpath options are included in the executable and used at runtime, whereas the -rpath-link option is only effective at link time." Based on this, it should be safe to remove these options from BUILD_LDFLAGS: these folders don't exist during runtime, but since they are present as rpath-link also in BUILD_LDFLAGS, they can be still used link-time, if needed. This allows generating reproducible binaries for this recipe.
