(e.g. NetBSD with bundled XFree86). Checking whether "X11_TYPE" is "xorg"
is obsolete and *not* equivalent to checking whether we are not using
modular X.org.
when X11_TYPE=xorg. Let them include x11.buildlink3.mk directly.
Remove the manual USE_BUILTIN declarations from xorg-libs/b3.mk.
This fixes a symmetry in the dependency list depending on whether
xorg-libs is installed already or not.
Discussed with jlam@
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
