    # Configure flag notes:    
    #   1. An attempt to stop anything going in $PREFIX/lib64 (which doesn't
    #      fully work; we will need to hobble the multilib configuration in
    #      config/i386/t-linux64 if we really want to kill /lib64).
    #   2. Multilib does not make sense in Baserock.
    #   3. Optimisation libraries which for now we do without.
    #   4. Recommended by Linux From Scratch; required for C++ ABI
    #      compatibility with other Linux distributions.
    #   5. MPFR is built in the GCC tree, we need to locate it.
    #   6. Avoid having more than one copy of ZLib in use on the system
