Repo-copy tools/regression/usr.bin/make to tools/build/make_checkand adjust the path in the Makefile for the upgrade_checks target.These checks are really feature upgrade checks that should be fastand just find out whether we need to build a new make beforeproceeding with other targets like buildworld. This makes theplace free for a real regression test suite in the old place.
Add some regression tests for the .SHELL target. I'm not sure that theoutput of shell_2j is actually correct - it just tests what make currentlydoes. Make should switch on echoing for the second line, shouldn't it?
