I favor the $(TOUCH) approach, and using a complex definition for
TOUCH on the broken machines.  It is a trivial transformation, it
solves the problem, and impacts the software minimally in a negative
way.

Gosh, while we can investigate this, we should not do it because of a
random stupid bug on Solaris.  If build times are within a few % of
the non stamp build, then it would be reasonable, if they are 4x
longer, then I am in no way in favor of doing this.  Making this type
of decision without supporting data would be bad.
