* acinclude.m4: Include ../config/tcl.m4 to pick up

standard Tcl configury bits.
        Remove all Tcl, Tk, Itcl, Itk, etc definitions.
        * configure.ac: Don't check if ../itcl exists when building
        gdbtk. It could be installed.
        Rewrite gdbtk configury to allow for using system-supplied
        Tcl and Tk. Gdbtk no longer requires build-time access to
        itcl and itk.
        * Makefile.in: Remove everything related to itcl and itk.
        Rewrite the Tcl bits for gdbtk to correspond to rewrite of
        configure.ac.
        Remove v850ice.o build rule.
        (ALL_TCL_CFLAGS): New convenience defintion. Change all
        gdbtk sources to use it.
        * configure: Regenerate.
