Log Message:
Observe the following:

	VAR=	a
	PTR=	VAR
	${PTR}?= b

Given these definitions, ${VAR} == "b" (unintuitively).  We can work
around this by doing:

	VAR=	a
	PTR=	VAR
	.for _v_ in ${PTR}
	${_v_}?= b
	.endfor

In this case, ${VAR} == "a" (as expected).

Use the second form of assignment in this changeset so that the expected
behavior happens for the "TOOL" name variables.  This fixes "recursively
defined" errors for some of the "TOOL" variables when the pkgsrc tool
replaces the system-supplied one.
