How did you configure GCC?  It seems you are building without bootstrap
and/or with custom CFLAGS (you lack any optimization).

Hi,
jumping in because I experience the same issue on Gentoo with a PPC32 ibook g4.

Here is my current gcc : 
Target: powerpc-unknown-linux-gnu

Here is the configure command line

I can attach the full log if it helps...
