I had some issues at one point with /rescue and dhclient that
specifically broke rebuilds.  Basically, crunchgen has never
been entirely happy with the dhclient makefile.  I added one
line to the dhclient makefile (The @true line below) that
seemed to address this.  Maybe it was insufficient?

Excerpt from /usr/src/sbin/dhclient/Makefile:
+  # Note: Must have some commands here to override the default build action
    ${OBJS}: all
+        @true
