I'm trying to build static binaries for net-tools-1.60, so they can run on their own on any system. I downloaded the source for net-tools from SourceForge and applied 3 patches. Then I compile successfully with make SHARED=0 CC='gcc -static'. The compiled binaries show as "statically linked" and some work, but some get "Segmentation Fault". Mainly arp and route are not working. I also tried LDFLAGS="--static" make -j 4, but the resulting binaries still show "dynamically linked".
This is on Ubuntu 16.04 with 4.4.0-64-generic kernel. Any ideas how to get this working?

Update So I just built the tools on an older Ubuntu 11.10 32bit. The resulting binaries are working fine on my Ubuntu 16.04 64bit. I think there might be a bug in 16.04.
