I'm not sourcing the env file.  I'll try that today but I don't expect 
it to matter.  I recognize most of those env variables and I don't 
believe they're relevant to building the kernel.  I'll try it though, 
just to be sure.

But I have little hope.  I'm duplicating a process that I already have 
working with powerpc-4xx.  But powerpc-e500v2 seems to work 
differently.  For example, in powerpc-4xx, in the env file, 
/opt/eldk-5.6/powerpc-4xx/environment-setup-ppc44e-linux I find:

    export SDKTARGETSYSROOT=/opt/eldk-5.6/powerpc-4xx/sysroots/ppc440e-linux

whereas with powerpc-e500v2, in the env file, 
/opt/eldk-5.6/powerpc-e500v2/environment-setup-ppce500v2-linux I find:


That looks to me like a string that is intended for replacement that has 
failed to be replaced.  In the environment file, it probably doesn't 
mean much.  But if there's a similar unreplaced trigger in the compiler 
or linker specs, that could be a blocker.

So... I /expect/ that sourcing the env file will cause breakage, 
although it might be a different sort of breakage since the LD 
definition depends on the value of SDKTARGETSYSROOT.
