Functional llvmpipe isn't a new dependency.  Every primary arch has had
it working since F17.  Two of the secondaries do too in F19.  I
appreciate not wanting to depend more on llvm - believe me I really,
really, really, do - but I don't think you get to use that as an out
here.

Sure, but arm also builds without -fstack-protector because it's plainly
unimplemented, which is a fairly major security regression compared to
every other architecture.

The conclusion one might draw is that there's no toolchain attention
being paid to arm at all.  Which doesn't inspire in me much confidence.
