You can start from the C version and move forward and check that you get the same result as starting with released Go binaries.

Unless you think Ken somehow backdoored the original C compilers to backdoor every C compiler in the world to backdoor the Go compilers that came about decades later. :-)

Seems simpler to just backdoor the linker/library archiver, that way almost all toolchains are backdoored. ;)
