As far as I know there's no such thing as "Sun make version 3.79.1".
You're either using Sun's make, or GNU make 3.79.1.  They are completely
different.

Good.

Every command make invokes, including one that involves $(MAKE), forks
another process.

I don't see how forking another process will help build times... in
fact it would slightly _increase_ build times since you need to
fork/exec another program, that needs to re-read all the makefiles,
etc.

This mailing list is for GNU make, not Solaris make.  If you have
questions specifically about Solaris make you need to ask on a Solaris
mailing list or newsgroup.

Cheers!
