  43 # you should not need to take any special action.  Otherwise, you
  44 # should set the environment variable HOST_SH to a POSIX-compliant
  45 # shell, and invoke build.sh with that shell.  (Depending on your
  46 # system, one of /bin/ksh, /usr/local/bin/bash, or /usr/xpg4/bin/sh
  47 # might be a suitable shell.)

 531     -C cdextras Set CDEXTRA to cdextras
 532     -D dest     Set DESTDIR to dest.  [Default: destdir.MACHINE]
 533     -E          Set "expert" mode; disables various safety checks.

 539     -m mach     Set MACHINE to mach; not required if NetBSD native.
 540     -N noisy    Set the noisyness (MAKEVERBOSE) level of the build:

 550     -r          Remove contents of TOOLDIR and DESTDIR before building.
 551     -T tools    Set TOOLDIR to tools.  If unset, and TOOLDIR is not set in

 863 #   a copy of ${toolprefix}make (this should work for everybody who
 864 #   doesn't override TOOLDIR via /etc/mk.conf);
 865 # * Failing that, search for ${toolprefix}make, nbmake, bmake, or make,
 866 #   in the PATH (this might accidentally find a non-NetBSD version of
 867 #   make, which will lead to failure in the next step);
