samples/seccomp: fix 31 bit build on s390
On s390 the flag to force 31 builds is -m31 instead of -m32 unlike on all (?) other architectures. Fixes this compile error: HOSTCC samples/seccomp/bpf-direct.o cc1: error: unrecognized command line option "-m32" make[2]: *** [samples/seccomp/bpf-direct.o] Error 1 Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Acked-by: Kees Cook <keescook@chromium.org> Signed-off-by: James Morris <james.l.morris@oracle.com>
