commit: http://git.busybox.net/busybox/commit/?id=922fdf65273f3047c1f60edee6af555cea1dd499
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

Apparently, some *BSD variants (and maybe some other OSes) does not define
SIGPWR signal.  So since commit 760fc6debcba8c, busybox fails to build on
such platforms.  Fix this.
