Summary: No "single-suffix" rules in V7, BSD make

You can't.  The concept of single-suffix rules were added by AT&T in
SystemV (version 1, even, I believe).  The code to do it is fairly simple --
a couple-dozen lines added to the doname() routine.  Don't ask me for
them; if you think about it, it'd be illegal for me to post a diff.

If you want to do that in BSD, then you either have to port a System V
make (and buy source, if you don't already have that).  The AT&T Toolchest
sells a "new make" described in the Portland Usenix proceedings that
does this, and more.  But be warned:  nmake isn't the make we all know
and love:  it's a much more complicated beastie.
