Well, I let it sit for a while and it got further, but now I am getting this:

rm -f lib.a
arm-linux-ar rcs lib.a errno.o ctype.o string.o vsprintf.o
make[2]: Leaving directory `/usr/src/linux/lib'
make[1]: Leaving directory `/usr/src/linux/lib'

In file included from entry-armv.S:20:

make[1]: *** [entry-armv.o] Error 1
make[1]: Leaving directory `/usr/src/linux/arch/arm/kernel'
make: *** [_dir_arch/arm/kernel] Error 2

Any ideas on this? So far I have ar, ld, and gcc linked to arm-linux-ar arm-linux-ld and arm-linux-gcc. Is there something else?
