With the below magic incantation darwin can host a linux targeted
compiler. Without the patch, nothing links due to unresolved externals
(for the config_gtfiles, darwin.c in my case):
ld: Undefined symbols:
_gt_ggc_r_gt_darwin_h
make: *** [cc1plus] Error 1
Tested on powerpc-darwin6.0 and on a powerpc-darwin6.0 X
i586-pc-linux-gnu by comparing the generated Makefile, and ensuring
they were right, and by ensuring the cc1plus built. I contemplated
checking this in as obvious, but decided against it.

Sorry, I had a different solution to the problem a couple days ago, but have
been distracted by our little sibcall hell... :-)
The problem is that config_gtfiles is accumulating files irrespective of
host/target, and darwin.c should only be added if it's a target. So this
patch makes it a target-only thing (no host files with trees to track so
far). If everybody agrees that this is the way to go, I'll put it in.

Ah, yes, that is cleaner and better, as then it is obvious how to add
build only or host only gt files. I look forward to seeing your patch
in the tree.

Your solution to the problem neglected to actually solve the problem.
:-(
I had assumed that it had, sorry for missing that the first time `round.
I applied the below obvious patch.

Ooops, thanks - I had a moment of doubt when checking it in, must
have scrambled when "cleaning up". The clearing of target_gtfiles
in configure.in can probably go away now too.
