The portable executable header has a field describing the machine type. The machine type should match the binary. So on i386 we should use IMAGE_FILE_MACHINE_I386 and on x86_64 we should use IMAGE_FILE_MACHINE_AMD64. The actual value is issued by the objcopy command invoked in scripts/Makefile.lib in depdendence of the value of EFI_TARGET.

The value is used both for EFI_STUB and for EFI_LOADER.
