Description of problem:
The 'g-ir-scanner' program invokes libtool in some codepaths.

Attempting to build GTK-VNC introspection data in Koji fails with myterious errors:

  ./libgvnc-1.0.la: file not recognized: File format not recognized


The file giscanner/dumper.py conditionally uses libtool:


    def _link(self, output, *sources):
        args = []
        libtool = get_libtool_command(self._options)
        if libtool:
            args.extend(libtool)
            args.append('--mode=link')
            args.append('--tag=CC')
            args.append('--silent')

        args.extend([self._linker_cmd, '-o', output])


So because of missing dependancy on libtool from gboject-introspection-devel RPM, libtool isn't added to the command line & thus it fails to link.

Thus gobject-introspection-devel should have 'Requires: libtool'.

Version-Release number of selected component (if applicable):
gobject-introspection-devel-0.6.5-1.fc12.x86_64

Also affects F13/14

How reproducible:
Always

Steps to Reproduce:
1. Attempt to build a library which runs g-ir-scanner as part of its build process, eg

/usr/bin/g-ir-scanner -v \
                --namespace GVnc \
                --nsversion 1.0 \
		--include GObject-2.0 \
		--strip-prefix=Vnc \
                --library=./libgvnc-1.0.la \
                --add-include-path=.. \
                --add-include-path=. \
                --add-include-path=. \
                --output GVnc-1.0.gir \
                -I.. \
                -I. \
		--verbose \
                --pkg=glib-2.0 \
                --pkg=gthread-2.0 \
                --pkg=gdk-pixbuf-2.0 \
                --pkg=gobject-2.0 \
                ./vncpixelformat.h ./vncframebuffer.h ./vncframebuffer.c ./vncbaseframebuffer.h ./vncbaseframebuffer.c ./vnccolormap.h ./vnccolormap.c ./vnccursor.h ./vnccursor.c ./vncconnection.h ./vncconnection.c ./vncconnectionenums.h ./vncconnectionenums.c ./vncutil.h ./vncutil.c
