[m-dev.] diff: Fix bug with --enable-decl-debug but no tracing

[Mark Anthony BROWN]

Estimated hours taken: 1

util/mkinit.c:
	Don't refer to MR_edt_root_node in the *_init.c files unless
	the `-t' option is given.  This avoids a link error when the
	compiler is configured for declarative debugging, but is
	invoked without tracing on.

Cheers,
Mark.
