Ok, so I've found the issue. tcpdump finds some pcap binaries it needs
in the host sysroot, which then provides links to host include paths and
as such, the failure.

The question, how do I fix it? Will I need to inherit native or
something like that, so a local version is built which then points to
the correct sysroot that the cross version can then make use of? I've
never really had to deal with anything like this before...
