To help investigate this issue, can you perhaps include the text of the full
build output when you run "make static". On my system I see libelf listed on
the linker flags when I run "make static", and things link properly. I'm
wondering how my setup may differ from yours.

Below is the full output after running make static from the ethtool folder in
examples.
