First I should point out that we do not have any configuration of ELDK
5.0 yet that supports the PPC4xx or PPC44x processors.  Yous, you can
use the powerpc configuration, but this is unsupported and you are on
your own if you run into any problems.

The option "-enable-target-optspace" should be enabled in the
configuration when building gcc, but thjis is impossible at the moment
due to a number of regressions in recent versions of GCC.  See for

So in short, it's a GCC bug for which we don't have a fix yet.

Note that the issue is still present in more recent versions f GCC
(like 4.6.x).
