[PATCH] Document Requires.private

[Tollef Fog Heen]

* Stepan Kasal 

| Hello,
|   I'd like to submit the attached patch to the man page pkg-config.1.
| 
| When discussing the usage of pkg-config in the util-linux-ng project,
| it took me long time before I formed an opinion that Requires.private
| is what we need.  Observe yourself:
| http://thread.gmane.org/gmane.linux.utilities.util-linux-ng/953
| 
| Documenting the Requires.private: tag in the man page will surely
| help the people which will be solving the same problem.

Thanks, applied.
