    <!-- Don't remove this until Binutils upstream resolves this issue.
         We can test by building Binutils on a complete system with
         zlib (libz.so) installed, passing enable-shared and
         without-system-zlib.  If the resulted libctf.so still links against
         libz.so (check with readelf -d) despite we are saying
         without-system-zlib, then the issue is still unresolved.  -->
    <para>Binutils building system relies on an shipped libtool copy to link against
    internal static libraries, but the libiberty and zlib copies shipped
    in the package do not use libtool.  This inconsistency may cause
    produced binaries mistakenly linked against libraries from the host
    distro.  Work around this issue:</para>
