I think you are mixing two type of things. U-Boot building as 32-bit
or 64-bit is one thing. How to build U-Boot is another thing. This
patch was to address the build.

Some day once U-Boot x86_64 support is mature, we can consider that.
Even if we only support 64-bit U-Boot as the 64-bit EFI payload, that
does not mean i386-linux-gcc cannot be used. '-m64' is required to
pass to such toolchain to cross-compile 64-bit codes correctly.
