Compiling for my C8000 (64 bit) failed:

This is after I enabled MLONGCALLS, without longcalls it failed, too. I'm now 
trying with binutils 2.23.1 instead of 2.22.

My C3600 (32 bit) doesn't even come that far, I get:

make: hppa-linux-gnu-gcc: Command not found
make: hppa-linux-gnu-gcc: Command not found
/usr/src/linux-3.9.0/scripts/gcc-version.sh: line 25: hppa-linux-gnu-gcc:

Sorry, GCC v3.3 or above is required to build the kernel.
make: *** [checkbin] Error 1

Any ideas?
