Where did the Go team say explicitly they are not interested in a
better build system?

They just said they are not interested in replacing the last very few
remaining bits of bash unless there is certainty that it wont break
the build in some system.

The current build system already provides facilities to do this, just
nobody has bothered to replace the last remaining bits of (ba)sh.

What is the unproven assumption? One of the Go devs already pointed
out that the current shell scripts don't work for (who knows what
reason) FreeBSD's default shell, even when they make no use of any
bash-specific features as far as anyone knows.
