I think you need to retain the fact that one needs to bootstrap, not just
build GCC. Thus "If your change is to code that is not in a front
end, or is to the C or C++ front ends or <code>libgcc</code> or
libraries, you must perform a bootstrap of GCC with all languages enabled
by default, on at least one primary target, and run all testsuites."
Ok with that change.
