Ah, I thought by mistake that you failed to compile makedumpfile.
Probably you should ask it to the elfutils community.

btw, if you can use makedumpfile with dynamic libraries, maybe you
can use the distribution's packages without building elfutils.
I'm not familiar with Debian/Ubuntu, but I built a makedumpfile on
an Ubuntu machine once with the following packages:
  libdw-dev libelf-dev zlib1g-dev libbz2-dev
and "make LINKTYPE=dynamic", please see FAQ.002 in README.
