Debian's official iproute2 packaging build says 'libelf-dev' [0], and having
libelf-dev installed should work ...
[...]
Build-Depends: bison,
debhelper (>= 10~),
flex,
iptables-dev,
libatm1-dev,
libcap-dev,
libdb-dev,
libelf-dev,
libmnl-dev,
libselinux1-dev,
linux-libc-dev,
pkg-config,
po-debconf,
zlib1g-dev,
[...]
Did you ran into this one perhaps [1]? Do you have zlib1g-dev installed?
