minimal/do: don't create a .did file until after a file is actually built. With the new "continue" feature on by default, it turned out that ctrl-c during a build, or a .do file returning an error, would mark a target as "built" even though it hadn't been. This would prevent retrying it when you started minimal/do again. Use a temp file instead. It's a little tricky: to prevent accidental recursion, we want to create a file before building, but clean up that file when starting the next session. And we rename that file to the actual .did file after building successfully. 2018-11-02 03:48:25 -04:00			`[ -e 'want-fail' ] && exit 1`
