arm.c (arm_override_options): If the user has not specified an ABI...

* config/arm/arm.c (arm_override_options): If the user has not specified an
  ABI, then default to AAPCS for the iWMMXt processor.
* config/arm/t-xscale-elf: Remove redundant multilib specifications.
* config/arm/t-xscale-coff: Likewise.
