cross-arm-elf-binutils build fail (SOLVED)

I was trying to use the cross-arm-elf-binutils and cross-arm-elf-gcc-base packages to do some ARM assembly and C programming, but gas was segfaulting:

12:16, in exp1 $ make -k
make -e -f flash-v1.make 
make[1]: Entering directory `/home/samwise/C-programs/elec2142/labs/exp1'

arm-elf-gcc -c -mcpu=arm7tdmi -O2 -g -Wall flash.c -o flash.o
arm-elf-ld  flash.o cstart.o   -o flash.elf
arm-elf-ld: ERROR: cstart.o uses hardware FP, whereas flash.elf uses software FP
arm-elf-ld: failed to merge target specific data of file cstart.o
make: *** [flash.elf] Error 1

I suspected it was a 64 bit issue as I'm using Arch64. So I tried to build the cross-arm-elf-binutils package using the PKGBUILD on the AUR, but I get a build error:

make[4]: Entering directory `/home/samwise/ABS/cross-arm-elf-binutils/src/binutils-2.17/gas'

make[1]: *** [all-gas] Error 2
make[1]: Leaving directory `/home/samwise/ABS/cross-arm-elf-binutils/src/binutils-2.17'
make: *** [all] Error 2

'array subscript is below array bounds' - could this be the source of the segfault? I'm new to cross-compiling and I understand it's finicky, however any help would be appreciated.
(I did once try Linux From Scratch, but gave up after I realized I had just compiled a compiler to compile my compiler and my head exploded)

OK I have it working with this patch to the PKGBUILD:
