...via passing libelf as a buildinput.

Motivation for this change

I want to attach some filters to my interfaces via tc

IF="enp4s0"
sudo tc qdisc add dev "$IF" clsact
sudo tc filter add dev "$IF" ingress bpf obj test_ebpf_tc.o section action direct-action

but this failed with

No ELF library support compiled in.
Unable to load program
Things done

just passed libelf as a buildinput then iproute's ./configure scripts picks it up.

I can make it optional if need be.

  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nox --run "nox-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Fits CONTRIBUTING.md.

Sorry, something went wrong.

x86_64-linux failure is a timeout building gcc. Let's ignore it since this built fine on master.
