Mark packages with no staged installation support explicitly \ 
(PKG_DESTDIR_SUPPORT=none).

Log message:
Set BUILDLINK_ABI_DEPENDS correctly (with +=, not ?=)
It turns out there were a lot of these.

Log message:
recursive bump from gettext-lib shlib bump.

Log message:
corrected HOMEPAGE URL (old URL no longer exists)

Log message:
Remove @dirrm related logic.

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:
Remove trailing spaces.

Log message:
Renamed BUILDLINK_TRANSFORM.* to BUILDLINK_FNAME_TRANSFORM.*, to make
clear that these variables are completely unrelated to
BUILDLINK_TRANSFORM.

Added a legacy check that catches appearances of BUILDLINK_TRANSFORM.*.

XXX: Where should incompatible changes in pkgsrc be documented?

Log message:
Set MAKE_ENV+=SHELL=${CONFIG_SHELL} for all gcc packages. Fixes SHELL set
to non sh compatible shell in environment. Thanks to Georg Schwarz.

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
