For crosstool-NG, that's not that easy. There is no top-level rule to just
do the download. crosstool-NG does its own downloading.

So, we have to build crosstool-NG, which implies building host-gawk and
host-automake, and their dependencies...

I've done the necessary stuff here, and will post a patch shortly after a
little bit more of testing...
