Log Message:
-add DESTDIR support, from Blair Sadewitz
 (I didn't adopt the libtool change for now because it is not clear for
 be whether that PAM modules is useful for non-NetBSD.)
-block SIGCHLD while the forked helper process is running, so that a
 calling process with a SIGCHLD handler won't steal the exit status
 which is used to report success of the authentication.
 This makes the "dropbear" ssh server usable if started with user
 privileges.
