Unable to build lsof likely due to recent toolchain bumps

[graysky2]

I am getting the following error when building an image with lsof enabled. Suspect something introduced with recent toolchain bumps.

same issue on my build, on os ubuntu 18.04

It is something missing in perl for new autotools.

I tried that patch and lsof still fails to build with:
