Log message:
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.

Update to 0.44:

2006-01-16  Jason Day <jasonday@worldnet.att.net>

    Version 0.44

    - Removed the -module argument from libmal_la_LDFLAGS. It never should
      have been there; it was accidentally included from a copy/paste.

Log message:
Remove obsolete patch (already removed from distinfo).

Log message:
Update libmal to 0.43

    Version 0.43
    - Several fixes to the last release.
    - OpenBSD patches from Antoine Jacoutot

    Version 0.42
    - Misc fixes to malsync sources. See malsync/ChangeLog for details.

    Version 0.41
    - Added support for pilot-link 0.12.x
    - Updated automake files

Log message:
Don't try and use <malloc.h>. Fixes build on FreeBSD 6.1

Log message:
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

Log message:
Track information in a new variable BUILDLINK_ORDER that informs us
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.
