# 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
