Some packages check for the pkg-config file for libmad. This file is particularly needed so that Cdrdao can recognize the installed libmad.

As the `root` user:

    cat > /usr/lib/pkgconfig/mad.pc << "EOF"
    prefix=/usr
    exec_prefix=${prefix}
    libdir=${exec_prefix}/lib
    includedir=${prefix}/include
