PR-108135 Remove PACKAGE_* definitions from gm2config.h

PR-108135 gcc/m2/configure generates gm2config.h and
automatically adds PACKAGE defines.  gcc/m2/Make-lang.in
now removes these PACKAGE definitions.  The patch also
contains fixes to remove an unused variable Dim from
BuildConstHighFromSym and also uses withTok in StartBuildWith.
StartBuildWith will generate a nop (for improved debugging)
if requested.

	* Make-lang.in (m2/gm2config.h): Rewrite rule to be
	dependent upon m2/gm2config.aci.
	(m2/gm2config.aci): Newrule.
