That is doing a lot less.  It compiles each of the PROGS from a
single .c file

It uses none of the _ features that this new proposal uses.

This new proposal will build one .o file, which is used for two build
products.  I suspect an #if statement can easily create problems.

Anyways, I think I can confidently predict using more of this will break
quickly, and I dislike this feature of bsd.prog.mk and don't think we
should be doing this.
