Attempting to use a toolchain that is preconfigured to generate code for the 32-bit architecture (i386), for example, the i386-linux-gcc toolchain on kernel.org, to compile the 64-bit EFI payload does not build. This updates the makefile fragments to ensure '-m64' is passed to toolchain when building the 64-bit EFI payload stub codes.
