I suggest that now it is a good time to use Aspectator (aspects less => almost like gcc) for building a kernel rather then a system compiler. I guess that it is rather easy, and Vladimir has already done this for using cross Aspectator on ARM. I think that there should be just one option for make, but of course this should be configurable (Aspectator by default).

BTW, please see at dirty hacks we have made in our Model DB. We will be able to avoid the most of them if we will switch to Aspectator as compiler.
