To: elfutils-devel
gnulib #defines all the types we need from it in config.h, so it is empty.
We still need it because other files #include it. We use this for building
elfutils itself. The other features.h in lib gets installed in selfcontained
mode for other projects that include elfutils headers in a different
environment.
