Kind of a good call. For some reasons with ppc I have to add -std=c99
to my CFLAGS if I compile with gcc-4.4.3 - note that it is not necessary
with gcc-4.3.4 on ppc or gcc-4.4.3 on x86. Just adding that got me to 
a further failure to lisp bootstrapping (that I had with gcc-4.3.4).

Removing all other flags however seems to have done the trick, so there
may be one that is dodgy to ecls in the lot.
I will see if building has finished later, cross finger :)
If it does I may take some time to see which flag(s) lead to the failure.
In the meantime I also asked for help from the ppc forum.
