Builds stripped with llvm-strip -S after this change don't run on arm64 macos anymore, while the build before strip runs fine. See for example the binaries in https://glandium.org/files/jsshell.zip . Download (with curl to avoid quarantine) and uncompress the file, then run ./js. It'll work. `llvm-strip -S` the binaries and it doesn't work anymore.
