yes. the Q you're asking is: "how was this bootstrapped?" the page that's referenced from GitHub doesn't describe that http://cm.bell-labs.co/who/dmr/primevalC.html http://cm.bell-labs.co/who/dmr/primevalC.html however there probably was a running c compiler (written in assembly) and an assembler and a linker available, hand bootstrapped from machine code, then assembler, linker, then B, NB and then C...
