Modified Files:
	basesrc/usr.bin/make: job.c job.h

Log Message:
Fixed race condition that would cause make -j to pause for five
seconds if a SIGCHLD arrived while make was not blocked in poll(),
by making the SIGCHLD handler write to a pipe included in the poll.
Avoided the need to implement a duplicate fix for the USE_SELECT case
by emulating poll() in terms of select() when USE_SELECT is defined.
Fixes bin/18895.
