[llvm-dev] LLD issue on a massively parallel build machine

Enable threads is for building llvm with or without thread support. To my
knowledge it has no effect on the build system.
Like was discussed above you could try limiting the number of processes
created (assuming your lld was after that commit) with numactl or taskset.
In your case though it looked like you were running out of memory. You
could try increasing your swap space?
