Needs to link with -lfl with new enough flex. Shouldn't hurt anyone
else, so do it unconditionally.

update to 2.0.16
changes:
Function attributes; simple destroy, finalize, construct override support;
afterdecls C block; minor other fixes/improvements.

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.

Log message:
update to 2.0.15
changes: Couple of minor fixes

Log message:
Add DESTDIR support.

Log message:
Update to 2.0.14, provided by Martin Wilke in PR/34439:
	* Fix major segfault
	* --no-touch support to avoid spurious rebuilds (see manpage)
          (Jean-Yves Lefort)
	* abstract class flag support (Jean-Yves Lefort)
	* allow BOXED in signal arguments (see manpage) (Big Thor)
	* fix libglade support (Nicolas Bruguier)

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.

Log message:
USE_TOOLS+=lex

Log message:
Aligned the last line of the buildlink3.mk files with the first line, so
that they look nicer.
