iproute2: simplify linking libelf for eBFP/XDP object file support
Simplify build and runtime dependencies on libelf, which allows tc and ip
to load BPF and XDP object files respectively.
Preserve optionality of libelf by having configuration script follow the
HAVE_ELF environment variable, used similarly to the HAVE_MNL variable.
