+cups-config, at least on Ubuntu Lucid and Natty, dumps all
+cflags/ldflags/libs when passed the --libs argument.  gyp would like
+to keep these separate: cflags are only needed when compiling files
+that use cups directly, while libs are only needed on the final link
+line.
+
+TODO(evan): remove me once
+  https://bugs.launchpad.net/ubuntu/+source/cupsys/+bug/163704
+is fixed.
