A few fixes for cross-building bpftool and runqslower, to build for example an arm64 bpftool on a x86 host machine and run it on an embedded platform. Also fix out-of-tree build, allowing for example to use the same source tree for different target architectures. Patch 1 factors the HOST variables definitions. Patches 2 and 3 fix the bpftool build and patches 4-6 fix the runqslower build. I also have some fixes for the BPF selftests build which I'll send later.
