Subject: Initial implementation of buildlink3, based on buildlink2 and
 designed to take advantage of pkgviews.

More thought is needed for the pkgviews/libtool interaction because
libtool archives (*.la) will likely contain absolute paths to other
.la files in depot directories, but we don't want this since binary
packages with wildcard dependencies may break.

+#
+# For *.la files, in the "relink_command" line, we make the following
+# replacements:
+#
+#       "libfoo.la" -> "-L./.libs libfoo.la"
+#	"dirpath/libfoo.la" -> "-Ldirpath/.libs libfoo.la"
+#
+# This allows the libraries to be found within ${WRKSRC} during relinking.
+# We rely on the proper rpath settings to be set by libtool.
+#
+# For the *.lai files, in the "dependency_libs" line, we remove redundant
+# -Ldir and -llib options.
