[PATCH v2 01/30] bsd-user: Add stubs for new signal routines

[Warner Losh]

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.
