This was my hope, and why I CC'ed Manuel so he could provide some insight
into why this might be failing....
My understanding is that the tooling library wishes to only run a single
compilation job, and is failing to properly set up the driver/invocation
for that, leaving the external assembler job also in the pipeline. I'm not
of the exact location of this code, but I think Manuel has seen related
problems recently anyways.
