None of the kernel versions will build.
I gave up on the xcopilot target, and decided to try to build
the Samsung S3C4510B target using arm-linux-tools-20070808.
There is no 2.6 or 2.0 configuration for the S3C4510, so I
tried to build 2.4. That fails:
OK, so I gave up on xcopilot, and I gave up on S3C4510.
There must be at least _one_ target that builds -- right?

Seriously. There is, isn't there?
Yes, there is at least one :-)
Here is what I tested (with vendor/product and specific
kernel version and libc) before I pushed up 20080808:

Next, I decided to try to build for the Snapgear LITE target.
Since I've got a couple Snapgear LITES sitting in a box
somewhere, I thought I'd try it next.
Here's how that fails:

I'm a little suspicious of that first line of output from
which. Why is looking for m68k-uclinux-20060615-gcc?
$ grep -r 20060615 .
./vendors/config/m68knommu/config.arch:ifneq ($(shell which
m68k-uclinux-20060615-gcc),)
./vendors/config/m68knommu/config.arch:CROSS_COMPILE = m68k-uclinux-20060615-
What's so special about that particular version of the
m68k-uclinux toolchain?
Should we not use a later toolchain?
The dist has been set up to allow multiple similar tool chanins
to be installed (thus the dated tool parts). But it will fall back
to the usual base type (ie m68k-elf-) if nothing else is installed.
Is using too recent a toolchain with m68k targets what causes
the thousands of warnings like these?
namei.c:2050: warning: matching constraint does not allow a register
namei.c:2050: warning: matching constraint does not allow a register
namei.c:2050: warning: matching constraint does not allow a register

That is the older 2.4 kernel code not being warning clean on
more modern versions of gcc. It is noisy, but otherwise seems
to work. You will get very few warnings if using the 2.6 kernel.
Are those warnings something about which I should be concerned?
I'm not sure if that complaint from "which" has anything to do
with the later failure which is caused by a non-existant
directory path being passed to mkdep:
-I /usr/local/lib/gcc/m68k-uclinux/4.1.1//include
That's wront because my toolchain is not installed in
/usr/local. I do development for several different targets and
OSes, and you can't assuming you can install things with names
like m68k-elf-gcc in /usr/local/bin without conflicts. So the
uclinux tools are installed in /opt/uclinux instead of
/usr/local.
But, I can't figure out where that bogus path is being set. The
most portable thing to do would be to do something like the
following (in bash syntax):
$(dirname $(${CROSS_COMPILE}-gcc --print-libgcc-file))/include
Anyhow, I'll add a symlink from /usr/local/lib/gcc/m68k-uclinux
and try again...
