# 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
