I haven't run into these pain points much with Make, but Knit does support spaces in targets/prerequisites (use single or double quotes to surround the name). For the second point, Knit has regex rules (a Plan9 Mk feature) that can allow multiple grouped matches. The example from the article is:

    $ ($name-(.*)-(.*)):RB:
        GOOS=$match2 GOARCH=$match3 go build -o $match1

which is a metarule that matches targets like `$name-linux-amd64` and can be used for easy cross compilation with Go. Of course since it allows full regular expressions, even more complicated rules are allowed.
