And to tack on my $.02 :)
We've gotten crossm68k working here and will make the port submission in a few minutes.
Our solution to gas is pretty simple, (and seems to be necessary for m68k)...
CONFIGURE_ARGS= --target=${TARGET} --with-gnu-as
When using this option, a symlinked crosstree-1.4 won't work for us, as it causes gcc to
look in ../gas for as.new -- It was necessary to create a 'real' crosstree directory.
Currently we do this using tar (with -h option) in a pre-configure step, pending public
release of crosstree-1.4. This approach takes a *lot* of disk space to say the least...
Perhaps this could be done with hard links, but I had the disk space to burn and very
little time. Maybe next update :)
It seems to me that this should work for other cross development targets.
Wondering if anyone knows the status of gdb-4.17? Presently, we use gdb-4.16 and a simple
patch to make it "work" with the other libs.
All of this has been lightly tested with some of our other software here. I would greatly
appreciate any feedback.

We're off working on a stub to facilitate remote debugging with Applied Microsystems
ES-1800 in-circuit emulators.
