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.

gcc/m2/ChangeLog:

	* Make-lang.in (m2/gm2config.h): Rewrite rule to be
	dependent upon m2/gm2config.aci.
	(m2/gm2config.aci): Newrule.
	* configure.ac (AC_CONFIG_HEADERS): Change destination
	to gm2config.aci.
	* configure: Regenerate.
	* gm2-libs/config-host: Regenerate.
	* gm2-compiler/M2GCCDeclare.mod (AddSymToWatch): Comment
	out.
	* gm2-compiler/M2Quads.mod (BuildConstHighFromSym): Remove
	Dim.
	(StartBuildWith): Call BuildStmtNoteTok.
	(BuildStmtNoteTok): New procedure.
	(BuildStmtNote): Re-implement re-factor into two
	procedures and call BuildStmtNoteTok.
	* gm2config.h.in: Remove.
	* gm2config.aci.in: New file.
