udev-config documentation

[Bruce Dubbs]

I was just reviewing the files installed bu LFS-6/5 and notice that the 
udev-config documentation is installed in /usr/share/doc/udev-config.

Shouldn't that be /usr/share/doc/udev-config-20090523?

We could change the install instruction in the book to:

export DOC_DIR=/usr/share/doc/&udev-config;
make -e install-doc
make -e install-extra-doc
unset DOC_DIR

or similar.  The above avoids any change to the udev-config tarball.  Other 
options would be to change the Makefile in that tarball.

Is this worth the effort?
