They are exactly that.

And that does fix the problem!

I think the problem is described by this page here:
http://alfix.gitlab.io/bsd/gnu/coding/2017/01/28/gnu-make-vs-bsd-make.html

Amongst other differences with FreeBSD make, it uses a different bracket type, 
like ${THIS}, and not like $(THIS).

I also found this guide to making cross-compatible Makefiles but I don’t know 
how useful it is: https://mmap.page/dive-into/make/
