Looks like the kdbus example never worked for the affected architectures.
I don't build allmodconfig for all architectures, so other architectures
may be affected as well.
You need 3.17 kernel headers to have memfd_create, not much the kdbus
test code can do about that. You might want to update the kernel
headers for these build boxes.
Or just 'make headers_install' before building the samples should do it.
Sure, that works so well in a cross build environment.
