From 1c9df6b4353dfc913c36628851bb83df0efec41e Mon Sep 17 00:00:00 2001

Subject: [PATCH] Don't build dependencies unless NOCLEAN is set.  This speeds
 up `make world' by about 14% here (down to 4490 seconds real on a K6/233). 
 Temporarily skip this optimization when building with -j, since there are
 still many broken makefiles.

Fixed NOCLEANDIR option.  Cleaning of `.depend' was broken.

Put -nostdinc in CFLAGS, not in CC, and don't override the default
CC.  This fixes enforcing use of ${WORLDTMP}/usr/include.

Don't install library man pages in ${WORLDTMP}.
