I haven't come across the problem you've described before.  Although I  
understand what the symptoms mean, but the root cause could be obscure  
and time-consuming to track down.

In order to build wombat for ia32_pc99, what I've done is create two  
symlinks:

$: ~/release/okl4_release_1.5.2$ ls -l linux/
total 4
drwxr-xr-x  4 nelson nelson   35 2007-09-30 09:16 apps
drwxr-xr-x 18 nelson nelson 4096 2008-03-21 18:18 kernel-2.6.10-v1
lrwxrwxrwx  1 nelson nelson   17 2008-03-21 18:19 kernel-2.6.11-v2 ->  
kernel-2.6.10-v1/
drwxr-xr-x  5 nelson nelson  131 2007-09-30 09:52 rootfs-2.6.10-v1
lrwxrwxrwx  1 nelson nelson   17 2008-03-21 18:19 rootfs-2.6.11-v2 ->  
rootfs-2.6.10-v1/
drwxr-xr-x  3 nelson nelson   22 2007-09-30 09:17 tools

(You could just as easily change the kernel_version variable in  
projects/iguana/SConscript to 2.6.10-v1).

Then doing a

     ./tools/build.py project=iguana machine=ia32_pc99 wombat=yes  
simulate

works for me.

One thing I've noticed is that you're using gcc-4, while we're using  
gcc-3.4.4.  I'm extremely wary of unpredictably different behaviour  
across tool versions, so I'd suggest using 3.4.4 and see if that makes  
a difference.
