The original build setup used a "fake GOPATH" in tools/golang to test the mechanism of building from go package files installed on a filesystem. With the move to modules, this isn't necessary, and leads to potentially confusing directories being created. (I.e., it might not be obvious that files under tools/golang/src shouldn't be edited.) Get rid of the code that creates this (now unused) intermediate directory. Add direct dependencies from 'build' onto the source files.
