Subject: [PATCH] configure.ac: Make the id3tag and mad checks check for both a
 header and the appropriate library if the pkg-config is...

Original commit message from CVS:
* configure.ac:
Make the id3tag and mad checks check for both a header and the
appropriate library if the pkg-config is missing. (Closes #331842)
Split the id3tag and mad checks into 2 pieces. Sometime soon I might
do the same for the plugins themselves.
