This error is unrelated to the referenced commit, but we did fix this error finally in 5.7: https://github.com/ClangBuiltLinux/linux/issues/515. This is not a regression, but something that never worked with LLD until 5.7. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7273ad2b08f8ac9563579d16a3cf528857b26f49 looks like the commit of interest, though I seem to have left a comment implying there were dependencies: https://github.com/ClangBuiltLinux/linux/issues/515#issuecomment-612999929 (I no longer recall what they were).
