    edk2: Update to not build libefivar for lib32 on amd64
    
    This dropped from the last commit because I had to redo it so many
    times...
    
    edk2 headers just aren't setup for the weird, hybrid enviornment we're
    compiling in when building i386 libraries for amd64 lib32. Since we
    can't use it there anyway (there's no 32-bit efibootmgr or efivar), and
    native i386 doesn't have them (we don't support EFI Runtime Services on
    i386 because we don't support EFI booting there).
