--- Comment #1 from Ian Lance Taylor <ian at airs dot com> ---
There is no internal/cpu.gox file in GCC 7, so something strange is going on. 
On current mainline internal/cpu exists, but the Makefile does not build it. 
You must have modified the libgo sources in some way.

I'm not sure I understand the question, but by the time libgo is being built,
gccgo is the final Go compiler driver.
