The nbmake-${MACHINE} wrapper is a very simple shell script, which
unconditionally sets USETOOLS=yes, and unconditionally sets many other
environment variables, overriding what you think you are passing in the
environment.  (By "unconditionally" I mean that the decision is made at
the time the wrapper is created by build.sh, not at the time the wrapper
is executed.)

Yes, overriding variables on the command line works better than in the
environment.
