iproute2: support eBFP/XDP object file loading, simplify linking libelf
Add build and runtime dependencies on libelf, allowing tc and ip-full to load BPF and XDP object files respectively. Define package 'tc' as a singleton package variant, which can be used to enable additional functionality limited only to tc. Also set ip-tiny as the default 'ip' variant. Preserve optionality of libelf by having configuration script follow the HAVE_ELF environment variable, used similarly to the HAVE_MNL variable. Signed-off-by: Tony Ambardar <itugrok@yahoo.com>
