However, I cannot seem to figure out how to get the '-v' command passed to LLVM's linker. Neither ninja's help output or some basic Googling seem to be helping me diagnose this issue, so I was wondering if anyone here could help?

I'd suggest checking /var/log/messages for further information. Is
this i386 or amd64, how much memory does your build host have, and are
you compiling with debug information or no? If had to guess, you're
running out of memory (or running into ulimit) during linking, and the
process is being killed as a result.
