I'm trying to compile the new toolchain using tool/tool_chain x86. However, it gives the following error:

If you have them, rerun configure with --enable-multilib. If you do not have them, and want to build a 64-bit-only compiler, rerun configure with --disable-multilib.
I don't need the 32 bit stuff. However, I have no idea in which configure scripts this should be put. What do I need to do to build the toolchain for 64 bit?
