Until the signal support is merged from the bsd-user fork, we need stubs
for cpu_loop_exit_sigsegv and cpu_loop_exit_sigbus to link. These call
abort after logging a message. Since singals aren't supported here
yet, this is sufficient.

I'm going to apply this directly to master as a build fix.
Sorry about that.

Works for me. I just cherry-picked and the build works with it.
