So if I'm not missing something important this will make the compat syscall
define available even for

CONFIG_X86_64=y
CONFIG_IA32_EMULATION=n
CONFIG_X86_X32=n

which is wrong because in that configuration we don't have any 32bit
executable support. So why would we need a compat syscall in that case?

Thanks,
