go: ensure use of BUILD_CC when building bootstrap tools

For cross-canadian builds, we were accidentally using
the crosssdk C compiler when building the Go compiler
bootstrap.  Add a patch to the make script to let us
use BUILD_CC, and prepend do_compile to set it in
the local environment to ensure that the trailing
blank gets stripped, since that confuses Go.
