This change fixes the compilation error triggered here for
i386 allmodconfig in linux-next:
http://kisskb.ellerman.id.au/kisskb/buildresult/6123842/
Logic attempting to predict the host architecture has been
removed from the Makefile. Instead, the bpf-direct sample
should now compile on any architecture, but if the architecture
is not supported, it will compile a minimal main() function.
This change also ensures the samples are not compiled when
there is no seccomp filter support.
(Note, I wasn't able to reproduce the error locally, but
the existing approach was clearly flawed. This tweak
should resolve your issue and avoid other future weirdness.)
