Until now building the x86 arch boards required 32-bit toolchain. As many x86_64 toolchains come with 32-bit support (multilib) that's a good idea to enable build with such toolchains. The change required was to specify the usage of 32-bit explicitly to the compiler and the linker (-m32 and -m elf_i386 flags) and locate the right libgcc path.
