No (Although maybe some people will argue that BSD make itself is obsolete...).
But what does it matter -- gnu make still understands them, doesn't it?

There are some implicit rules, and variable expansions can be used,
but many of the GNU constructs are not supported. See make(1), and:

Patterns and the foreach function:

You can limit yourself to constructs common to both makes, but if you
prefer gnu make, then why not just write makefiles accordingly and use
gmake from devel/gmake?
