Extracting test result isn't easy, and creating these initramfs and kernel
images are time consuming. qemu-user may be a better choice, I'm not sure
about the stability of qemu-user though. The following shows qemu-user
could easily run a simple userspace program of a different architecture:

hoolala@ubuntu:/tmp$ cat hello.c
#include <stdio.h>

int main() {
    printf("hello\n");
    return 1;
}
hoolala@ubuntu:/tmp$ arm-linux-gnueabi-gcc hello.c -static
hoolala@ubuntu:/tmp$ qemu-arm ./a.out
hello
hoolala@ubuntu:/tmp$ echo $?
1
