I don't see that here -- instead, I get this, with or without this patch:

$ CROSS_COMPILE=powerpc-linux- ./MAKEALL kilauea
Configuring for kilauea board...
powerpc-linux-ld: u-boot: section `.text' can't be allocated in segment 0
powerpc-linux-ld: final link failed: Bad value
make: *** [u-boot] Error 1

This is with binutils 2.18.  Do I need to upgrade?

     ppc4xx: Add common ppc4xx linker script

     This linker script can be used by all PPC4xx platforms. It works for
     PPC405 and PPC440 platforms. Boards which need a board specific linker
     script can override this default linker script in board/*/config.mk.

Can you post a full boot log of your error?  I'm guessing host crc32.o is 
getting linked into target code or vice versa, though I don't see why that would 
happen only on 4xx.  One should be tools/crc32.o and the other should be 
lib_generic/crc32.o.
