    <title>Installation of Pkg-config-lite</title>

    <para os="a">Several packages in the temporary system will use
    <command>pkg-config</command> to find various required and optional
    dependencies. Unfortunately, this could result in those packages
    finding libraries on the host system and trying to link against them,
    which will not work. To avoid this problem, we will install
    a <command>pkg-config</command> binary in
    <filename class="directory">/cross-tools</filename> and configure it so
    that it will look for Pkg-config files only in
    <filename class="directory">/tools</filename>.</para>
