First, did you actually download the binaries from our web site? 
Sometimes other people try to build them, and they don't always get it 
quite right -- that's why we have the binaries. :-)

Second, you should link with "arm-none-eabi-gcc", not "arm-none-eabi-ld".

As with the command-line example I showed you earlier:

bash-3.00$ arm-none-eabi-gcc -c test.c
bash-3.00$ arm-none-eabi-nm test.o
         U __aeabi_idivmod
00000004 C i
00000004 C j
00000000 T main
bash-3.00$ arm-none-eabi-gcc test.o

Yours,
