+Subject: [PATCH] utils: link using libcap-ng.la
+
+When linking internal dependencies that were linked using $(LIBTOOL) the
+ideal method is to use the generated libtool archive (.la) file. This
+fixes the build with slibtool which doesn't find -lcap-ng during the
+build and explicitly requires the .la file to be used.
