binutils/binutils: remove faulty patch

The added code should be conditinal to the target system
being !MIPS, but is based on the host system being !MIPS.

This is plain wrong, and had not been noticed until now
as I never used those binutils versions on MIPS.

     4 * arm.c (arm_legitimate_index): Only accept addresses that are in
     5 canonical form.
     6 * predicates.md (arm_reg_or_extendqisi_mem_op): New predicate.
     7 * arm.md (extendqihi2): Use arm_reg_or_extendqisi_mem_op predicate
     8 for operand1.
     9 (extendqisi2): Likewise.
    10 (arm_extendqisi, arm_extendqisi_v6): Use arm_extendqisi_mem_op
