OK, I narrowed it down a bit.  It looks like
 cd patches
 cp glibc-2.3.2/arm-ctl_bus_isa.patch glibc-2.2.5/
 mkdir gcc-3.4.1
 cp gcc-3.4.0/gcc-3.4.0-arm-lib1asm.patch gcc-3.4.1/
will fix the build breakages you were seeing with gcc-3.3.4
and gcc-3.4.1.  All I did was grep for the error message
in patches/*, pretty much.

Let me know if that helps.
