ffmpeg | branch: master | Stefano Sabatini <stefasab at gmail.com> | Mon Dec 17 13:39:53 2012 +0100| [9bba683578006ca7a17cb929f16eef58b68a3e08] | committer: Stefano Sabatini

doc/Makefile: add docclean rule

This allows to clean the doc directory from the parent project dir.
The command:
make -C doc clean

does not work as long as the paths specified in doc/Makefile are relative
to the parent dir.

Also it is consitent with "testclean" and "distclean" targets.
