Well, like I said, at the moment there's a choice of using the system
binutils or the cross-binutils port. The compiler isn't actually
intended to be a cross compiler but a native amd64 compiler (the
lang/gnat-gcc* ports have been marked as i386-only for ages). I'm not
sure if it's possible to tell GNAT where to look for binutils at
runtime.

I have some patches to send to both Adacore and the GCC developers to
add support for FreeBSD amd64.

I decided to use the system binutils because in order for someone to
actually build the port, they have to use bootstrap compiler binaries
provided by me (the gnat-gcc* ports do the same thing) and having those
binaries depend on a moving target like cross-binutils might create even
more complications.

I'll be providing full documentation and build scripts to show how the
bootstrapping compiler was created so if someone feels the need to use
the cross-binutils port, they can.
