The != operator has appeared in GNU Make 4.0 (released in 2013), but the GNU Make version on macOS is 3.81 from 2006 (lol). This should not cause issues in the immediate future because right now Mycorrhiza is pure Go and can be cross-compiled from a proper OS, but it will cause issues once it starts linking with C libraries (such as sqlite) and you won't be able to easily compile it for any OS without a C cross-compiler anymore.
