Using crossbuild

x86_64

$ docker run --rm -v $(pwd):/workdir multiarch/crossbuild make helloworld
cc helloworld.c -o helloworld
$ file helloworld
helloworld: ELF 64-bit LSB  executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=9cfb3d5b46cba98c5aa99db67398afbebb270cb9, not stripped

Misc: using cc instead of make

$ docker run --rm -v $(pwd):/workdir multiarch/crossbuild cc test/helloworld.c
