How's this all going?
I'm updating lang/gnat to gnat-2009 right now. In the
GNAT sources, it has build instructions including how
to build the cross - see below.

--------------------------------------
-- BUILDING GNAT - EXAMPLE SEQUENCE --
--------------------------------------
Supposing you have one tarball for the GCC sources and one for the GNAT
sources, here is a possible way to proceed:
0/ If not available on your system, build libgmp and libmpfr following
build instructions from these packages.
1/ Create a root directory into which you'll later setup the source and
build subdirectories:
~ $ mkdir GNAT
~ $ cd GNAT
2/ Setup an initial source tree from the GCC and the GNAT tarballs:
~/GNAT $ gzip -dc [...]/gcc-4.3*.tgz | tar xf -
~/GNAT $ mv gcc-4* src
~/GNAT $ cd src
~/GNAT/src $ gzip -dc [...]/gnat-xxx-src.tgz | tar xf -
~/GNAT/src $ mv gnat-xxx-src/src/ada gcc
~/GNAT/src $ patch -p0 < gnat-xxx-src/src/gcc-43.dif
~/GNAT/src $ touch gcc/cstamp-h.in
3/ Prepare and configure the build tree:
~/GNAT/src $ mkdir ../obj; cd ../obj
~/GNAT/obj $ ../src/configure --enable-languages="c,ada" --disable-libada ...
[see the GCC documentation for other relevant configure options]
4/ Build the compiler, run time and tools:
Note that the use of "GNU Make" is required by the GCC Makefiles.
~/GNAT/obj $ make bootstrap
~/GNAT/obj $ make -C gcc gnatlib gnattools
If you are building a cross compiler, you will need to replace
the above sequence by something similar to:
~/GNAT/obj $ make
~/GNAT/obj $ make -C gcc gnatlib cross-gnattools ada.all.cross
5/ Install the whole package:
~/GNAT/obj $ make install
