It depends on which make you are using. There are a couple of different
ones shipped with IRIX. My 2c is that the Samba4 build should simply
require GNU make and use all of it's features.

If you are using {p,s}make, you can use this syntax:
	ALL != echo "all"

IRIX make also supports a #! syntax, so you can select a particular make
by having this as the first line in your Makefile:
	#!gmake
