Currently it's needed to have gcc-multilib on the host to correctly compile xdp-tools. This is wrong and means that we are using host header to compile a tool. By some searching in how the makefile works it was discovered that BPF_CFLAGS were not used and required to be appended to config.mk Only one single header was added but we should include each BPF_CFLAGS from bpf.mk. To make this some patching to bpf-header were required and some patches to xdp-tools were required. Also it's needed to pass the correct target to BPF_CFLAGS. With the following changes xdp-tools can correctly compile with each header from bpf-headers and should not use any host header.
