Your problem is that you are trying to use Old ABI. IWMMXT needs to have
new ARM EABI or IWMMXT ABI
which was an intermediate step before ARM EABI was finalised.
adding -mabi=iwmmxt might fix your problem. may be --with-abi=iwmmxt in
gcc configure can do this for you.
You can enable EABI in your toolchain builds by
selecting proper target triplets
You can build an EABI toolchain using GCC 4.1 glibc 4.x and binutils 2.16+
if you want to use older versions you might have to apply some patches
