x86: Reject x32 executables if x32 ABI not supported
It is currently possible to execve() an x32 executable on an x86_64
kernel that has only ia32 compat enabled. However all its syscalls
will fail, even _exit(). This usually causes it to segfault.
Change the ELF compat architecture check so that x32 executables are
rejected if we don't support the x32 ABI.
