Due to clashes in the namespace between the Linux Kernel headers and the netinet headers building arptables with the musl C library fails. Best advice from the musl developers is to not include both headers in a userspace tool (see the thread on the musl mailing list [1], especially [2]). Since arptables only requires a few definitions from the Linux Kernel headers we opt-out the clashing header files and define the needed definitions. Patch sent upstream [3].
