[Patch] Select <External Makefile> the first time the build window is opened

[Mo DeJong]

Here is a simple patch that will select the <External Makefile> target
the first time the build Window is opened. I seem to remember this
working in the 4.5 version but it became broken at some point during
the 5.0 development cycle.

Since this is a small change I assume it will be covered by the
"Small changes can be accepted without a copyright
assignment form on file" text from the contrib webpage.

	* gui/makepane.tcl (Make): When initially
	opening the build window select the
	<External Makefile> target.
