  Have distrib-dirs, distribution, hier, hierarchy, redistribute, and reinstall
  depend on the .MAKE special target

  This will allow users to do something like the following to print out the
  results of the running the simulated make target with bmake, like some of the
  other top-level make targets in Makefile.inc1:

    % make -f Makefile.inc1 -n distribution TARGET=i386 TARGET_ARCH=i386

  Set the autoindent to 4 spaces with vim in BSD.tests.dist

  This will prevent vim users from accidentally checking in buggy mtree files
  (mixed tabs/spaces).
