How about "if you want to introduce a new bug, you have to fix one first"?
Serious, if we understand enough of this mess to fix it, we should fix it.

Looking into the "foo: bar" vs. "foo: ; ${MAKE} bar" you mentioned, one
thing that needs to be considered that for bar, the make() function
evaluates to a different value, and that's used esp. in the .USE macros.
See the Makefile below for a stripped down example.

P.S.: for the "make readme" someone mentioned, there is a solution that
      exchanges long waiting times by putting a lot of processes on the
      machine, see what FreeBSD have. I've played with it, but did not
      get anywhere I was satisfied with.

foo:    bar
        ${MAKE} bar

.if make(foo)
        @echo all: make foo
        @echo all: make not foo
