Committed: declare kill for CRIS

[Hans-Peter Nilsson]

I just committed this, needed for a recent gcc trunk change, for
the cris-elf port to build at all.  See earlier post and
committed patch for the general sys/signal.h.  It causes no
regressions compared to results before that change.  The CRIS
port overrides sys/signal.h and needs to be manually kept in
sync with visible functionality changes like declarations, see
top comment.

	* libc/machine/cris/sys/signal.h (kill): Declare.
