Could you help me out or give some advice?
(what kind of flags/files/ENVs should I have?)

I try that the the make process goes fine. My
custom part of "configure" is 

--target=powerpc-eabi
--prefix=/tmp/pun \
--exec-prefix=/tmp/pun/H-i686-pc-linux-gnu \

but I get the following error. 


The following are the errors
