>Description:
        If package indirectly includes mk/x11.buildlink3.mk, some
        builtin.mk files are not read.  For example, x11/randrext:

# cd /usr/pkgsrc/x11/randrext
# grep x11.buildlink3.mk Makefile
# make show-var VARNAME=BUILDLINK_PACKAGES
xorg-libs xextensions fontconfig iconv zlib freetype2 expat
# make show-var VARNAME=BUILDLINK_BUILTIN_MK.xextensions
../../x11/xextensions/builtin.mk
# make show-var VARNAME=BUILDLINK_BUILTIN_MK.zlib

# make show-var VARNAME=IS_BUILTIN.zlib

#

        This package indirectly includes mk/x11.buildlink3.mk via
        x11/xextensions/builtin.mk.  And this adds inclusions of
        buildlink3.mk files of zlib, fontconfig, etc.  However,
        these BUILDLINK_BUILTIN_MK are not defined.

        If the package is added to BUILDLINK_PACKAGES,
        BUILDLINK_BUILTIN_MK.${package} should be defined at line
        108 of mk/buildlink3/bsd.buildlink3.mk.  It's too late to
        include the buildlink3.mk files.
