Ugh, that could be a bit nasty.  I might be misremembering, but
my hindbrain is running for cover and yelling something about how
importing libbsd changes signal semantics.  Our git log has a few
scary references to other bad side-effects of -lbsd (cf 55c235b26,
1337751e5, a27fafecc).  On the whole, I'm not excited about pulling
in a library whose entire purpose is to mess with POSIX semantics.
