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.

Looks like this doesn't apply cleanly and thus needs a rebase. Pls submit a
v2, thanks!
