There are a few dependencies like libc. I would have guessed these
would have been picked up from the system, but perhaps I misunderstand
how this works.

# ldd usr/bin/portable-walkthrough-go
    linux-vdso.so.1 (0x00007ffe4c37a000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fcb0e400000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fcb0e697000)
