Olof's build test setup keeps failing to compile arm64 kernels because of a toolchain that uses outdated kernel headers:
/work/build/batch/samples/seccomp/bpf-fancy.c:13:27: fatal error: linux/seccomp.h: No such file or directory
This is of course something he could change, but it also indicates that others may run into the same problem. Running 'make headers_install' avoids the issue by ensuring that the kernel headers are put into the $(objdir)/usr/include path before we build the samples.
The same problem happened for the Documentation build in the past and was fixed up with commit 8e2faea877eb ("Make Documenation depend on headers_install"). This adds an identical Makefile dependency for the samples/ subdirectory.
