+    #   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
