In ROCK Linux we always had working cross-compile functionality since
we support cross build (of selected packages). We even do build a
"pseudo" cross compile for native builds (e.g. to have a clean
compiler for the real gcc build - and for system that have an old gcc
and the new glibc-2.3 is selected to build).

We had this code:

        if [ "$pkg" = "gcc2" ] ; then
                make -C gcc all LANGUAGES="c"
                make -C gcc install LANGUAGES="c"
        else
                make all
                make install
        fi

Which I now changed to:

        if [ "$pkg" = "gcc2" ] ; then
                make -C gcc all LANGUAGES="c"
                make -C gcc install LANGUAGES="c"
        else
                make -C gcc all
                make -C gcc install
        fi

And this seems to work for the 3.3-prerelease. I still need to test if
this still works for the current stable 3.2.x branch ...
