i believe this is a problem i solved with linking:
ln -s /lib/ld-linux-armhf.so.3 /lib/ld-linux.so.3
hopefuly it helps somebody at some point.

It seems a problem similar to #1208.
Linking the library should solve the problem.

@umbynos you may check if the mdns-discovery could be built without CGO enabled.
