+Disable the build of the po/ directory
+
+Building the po/ directory complains that the scripts in there have
+been generated with gettext 0.17, while we use gettext 0.18 in
+Buildroot. Since we don't care that much about po files anyway, just
+disable the build of this directory.
+
+Based on the former patch by Thomas Petazzoni.
