Update to the latest stable upstream version. Drop unneeded make variables to remove redundant assignments seen during invocation of package Makefile. Also remove the following patch now included upstream: * 200-fix-install-param-order-on-macos.patch Compile and run-tested on malta/mips32be, using bpftool directly and also libbpf (linked with tc) to inspect and load simple eBPF programs.
