Hi,
my build test machinery chokes on samples/seccomp when cross compiling
s390 and ppc64 allyesconfig. This has been the case for quite some
time already but I never found time to look at the problem and report
it. It seems this is not new issue and similar thing happend for
MIPS e9107f88c985 ("samples/seccomp/Makefile: do not build tests if
cross-compiling for MIPS").

The build logs are attached.

What is the best way around this? Should we simply skip compilation on
cross compile or is actually anybody relying on that? Or should I simply
disable it for s390 and ppc?
