Change the format of BUILDLINK_ORDER to contain depth information as well, and add a new helper target and script, "show-buildlink3", that outputs a listing of the buildlink3.mk files included as well as the depth at which they are included. For example, "make show-buildlink3" in fonts/Xft2 displays: zlib fontconfig iconv zlib freetype2 expat freetype2 Xrender renderproto 2006-07-09 01:10:35 +02:00			`#!/bin/sh`

Simply and speed up buildlink3.mk files and processing. This changes the buildlink3.mk files to use an include guard for the recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS, BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of enter/exit marker, which can be used to reconstruct the tree and to determine first level includes. Avoiding := for large variables (BUILDLINK_ORDER) speeds up parse time as += has linear complexity. The include guard reduces system time by avoiding reading files over and over again. For complex packages this reduces both %user and %sys time to half of the former time. 2009-03-20 20:23:50 +01:00			`# $NetBSD: show-buildlink3.sh,v 1.2 2009/03/20 19:25:01 joerg Exp $`
