+Subject: [PATCH 04/39] 64-bit multilib hack.
+
+GCC has internal multilib handling code but it assumes a very specific rigid directory
+layout. The build system implementation of multilib layout is very generic and allows
+complete customisation of the library directories.
+
+This patch is a partial solution to allow any custom directories to be passed into gcc
+and handled correctly. It forces gcc to use the base_libdir (which is the current
+directory, "."). We need to do this for each multilib that is configured as we don't
+know which compiler options may be being passed into the compiler. Since we have a compiler
+per mulitlib at this point that isn't an issue.
+
+The one problem is the target compiler is only going to work for the default multlilib at
+this point. Ideally we'd figure out which multilibs were being enabled with which paths
+and be able to patch these entries with a complete set of correct paths but this we
+don't have such code at this point. This is something the target gcc recipe should do
+and override these platform defaults in its build config.
+
+Do same for riscv64 and aarch64
