Snap-seccomp fails tests on artful (is it?)

The compile failure seems to be caused by the -m32 command line argument to gcc:

zyga@fyke:~$ gcc -std=c99 -Werror -Wall -static /tmp/check-6185516270145770849/1/seccomp_syscall_runner.c -o /tmp/check-6185516270145770849/1/seccomp_syscall_runner.m32 -Wl,-static -static-libgcc

The program that fails to compile is:

#include <sys/syscall.h>
#include <unistd.h>
int main(int argc, char** argv)
{
    int l[7];
    for (int i = 0; i < 7; i++)
        l[i] = atoi(argv[i + 1]);
    // There might be architecture-specific requirements. see "man syscall"
    // for details.
    syscall(l[0], l[1], l[2], l[3], l[4], l[5], l[6]);
    syscall(SYS_exit, 0, 0, 0, 0, 0, 0);
    return 0;
