Minor annoyance with bmake

[Jason Bacon <outpaddling%yahoo.com@localhost>]

There's been an intermittent issue running multiple targets with bmake 
for as long as I can remember:

Sometimes only the first target runs and sometimes all targets work.

I see the same issue with NetBSD's make.

For example, "bmake clean patch" only runs the patch phase if there was 
no work directory to begin with.

I assume others have experienced this, but is there an explanation? Is 
this something we should fix?

Hmm...?? Looks like a unified diff to me...
