Yes. The gdb port for FreeBSD has 'USES= gmake' in its Makefile (and has
for a long time). I use gmake for all of my development builds out of git as
well.
https://svnweb.freebsd.org/ports/head/devel/gdb/Makefile?revision=418964&view=markup#l18
I checked NetBSD (pkgsrc) and OpenBSD (ports) and they both build with gmake
as well. I had already assumed gmake was required FWIW.
