 which "this"?
 2., first paragraph, is needed. apb pointed out that it's even documented
 in some comment of the tools/Makefile:
 # For each .WAIT point, make sure the immediately preceding target is
 # installed before building anything after that point.
 # (dsl: which means that with: 'a b .WAIT c' the build of 'c' waits for the
 # install of 'b', but not the install of 'a'.)
 Given this, my 2nd paragraph is bogus.
 I've committed the above patch, because I didn't see your message in
 time; feel free to do corrections if needed.
