Short summary:

As shipped and as directed, (meaning, sourcing the env file), the 
eldk-5.6 toolchain for powerpc-e500v2 can't build u-boot.  Or at least, 
it can't build the u-boot/tools/env portion of u-boot.  This can serve 
as a regression test for this bug.  (I'm surprised this wasn't done 
already).

This can be traced to a bad directory reference in the env file, 
"--with-sysroot=/opt/eldk-5.6/powerpc-e500v2/sysroots/ppce500v2-linux" 
which doesn't exist.  It's not clear whether this directory is missing, 
(and should have been included which seems most likely), or whether this 
value should have pointed to a directory which /was/ shipped, (perhaps 
ppce500v2-linux-gnuspe).

I haven't been into the source, but I'd start with how the env file is 
configured and/or produced.  That should likely expose whether the 
directory is missing or badly pointed.
