I actually believe that preferring `gmake` *is* the right thing to do because we are (for whatever reason) looking for *GNU* make, and `gmake` (unlike `make`, it seems) is very likely to be the a "gnu make" -- if it exists. It's true that this would mean we use the name "gmake" on systems that usually call it "make" but so what... maybe we'll educate some people.

Conditionalizing it on the platform (particularly on the *target* platform) seems wrong. I think it be better to stick to the "gmake, make" order, and then check whether the thing we found was actually a GNU make (through `make --version` I guess) -- if it's not then issue a warning/error or whatever.

FWIW, the Mac make is not just "GNU compatible". It *is* GNU:
```
$ which make
/usr/bin/make
$ make --version
GNU Make 3.81
