[PATCH] Fix output when there are no --cflags or --libs to report

[Anthony G. Basile]

From: "Anthony G. Basile" <basile at opensource.dyc.edu>

When pkgconf parses a package for its --cflags or --libs and finds
none, it returns nothing.  In contrast, pkg-config [1] returns a
single blank char.  Packages, like rrdtool [2], assume this latter
behavior and fail to configure with pkgconf.
