Greetings Rob,
Trying to attempt such a goal would be quite cumbersome. Much more so
then just a little work
on the part of your algorithms.
There would be rebuilding a whole lot of open source software and
clubbing it over the
head to convince that it even tho you've passed powerpc-linux to
configure, you really meant
little endian.
It's just not worth it...
Regards,
Tom
