OK, that's not really supported I guess.

If you're happy building on your host system, you can do:

$ make -C tools/testing/selftests/ TARGETS=x86 install

And then you'll have:

$ find tools/testing/selftests/install/
tools/testing/selftests/install/
tools/testing/selftests/install/x86
tools/testing/selftests/install/x86/mpx-mini-test_64
tools/testing/selftests/install/x86/iopl_64
tools/testing/selftests/install/x86/sysret_rip_64
tools/testing/selftests/install/x86/protection_keys_64
tools/testing/selftests/install/x86/sysret_ss_attrs_64
tools/testing/selftests/install/x86/syscall_nt_64
tools/testing/selftests/install/x86/test_mremap_vdso_64
tools/testing/selftests/install/x86/ioperm_64
tools/testing/selftests/install/x86/ptrace_syscall_64
tools/testing/selftests/install/x86/sigreturn_64
tools/testing/selftests/install/x86/fsgsbase_64
tools/testing/selftests/install/x86/5lvl_64
tools/testing/selftests/install/x86/check_initial_reg_state_64
tools/testing/selftests/install/x86/ldt_gdt_64
tools/testing/selftests/install/x86/single_step_syscall_64
tools/testing/selftests/install/x86/test_vdso_64
tools/testing/selftests/install/run_kselftest.sh

You can rsync that wherever, and run it manually or with the
run_kselftest.sh script.

cheers
