You mean their ports scripts? Can you provide some url for reference?
John, could you comment from the FreeBSD side?

I (and others) have argued before about requiring GNU Make. I think
last was here:
https://sourceware.org/ml/binutils/2014-05/msg00263.html
I think it makes a lot of sense. FWIW, whenever I build GDB on the compile
farm on some non-GNU machine, like FreeBSD, AIX, NetBSD, etc., I've always
used the preinstalled GNU make.
Time to just do it? We'd need a NEWS entry, I suppose.
