When building bjam, with "./build.sh", you don't need to use your embedded compiler. bjam is purely
host binary, it does not know anything about the compiler that will be used later.

Yes, so you build bjam for the host.

After you've build bjam for the host, you follow instructions at:

        http://www.boost.org/boost-build2/doc/html/bbv2/tasks/crosscompile.html

which shows both where to specify the compiler command, and how to request that this
compiler be used. Did you try those instructions?
