Log message:
bsd.pkg.mk adds RPATH_FLAG to CONFIGURE_ENV so no need
to add it here.

Log message:
If we're passing through MAKEFLAGS variables whose values may contain
spaces, use the :Q modifier instead of double-quoting the value.  This
avoids breakage when executing the just-in-time su targets.

Log message:
Make PREFER_PKGSRC just yes/no or a list of packages.  This makes it
simpler to understand.

Log message:
Rename BUILDLINK_PREFER_PKGSRC to PREFER_PKGSRC so that we can use its
value outside of buildlink-related files.

Log message:
Support a new global variable:

BUILDLINK_PREFER_PKGSRC
	This variable determines whether or not to prefer the pkgsrc
	versions of software that is also present in the base system.

	This variable is multi-state:
		defined, or "yes"	always prefer the pkgsrc versions
		not defined, or "no"	only use the pkgsrc versions if
					needed by dependency requirements

	This can also take a list of packages for which to prefer the
	pkgsrc-installed software.  The package names may be found by
	consulting the value added to BUILDLINK_PACKAGES in the
	buildlink[23].mk files for that package.

Log message:
replace deprecated USE_GMAKE with USE_GNU_TOOLS+=make.

Log message:
Support BUILDLINK_DEPENDS.<pkg> being a list of values.

Log message:
Make sure that <freetype/freetype.h> is found.  Also if we use the
XFree86-supplied freetype2, then set USE_X11.

Use S/+$// instead of C/\+$// to save a backslash.  Very highly
recommended by seb :)
