If you're now getting clang: error: unable to execute command: posix_spawn failed: Exec format error
when ld is running, you're probably using Dave Levin's fake ld script without a she-bang line. Add "#!/bin/bash" to the first line of your /usr/bin/ld script in that case. (Or, if you're using the make build, ld is now serialized by default, so you can just mv /usr/bin/real-ld back to /usr/bin/ld.)
