[Buildroot] [git commit] package/iproute2: add optional support for elfutils

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=5da3186efbeeff49ea4dc1774280d7cc2899c27f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When elfutils was compiled before, iproute2 will use it as optional
dependency:

$ output/host/usr/bin/x86_64-linux-readelf -a output/target/sbin/tc | grep NEEDED
 0x0000000000000001 (NEEDED)             Shared library: [libelf.so.1]
[...]

The build system offers no option to en-/disable elfutils support:
