complibs: noone is using companion libs on the target; nuke them

As there's no longer any user of the companion libraries on the
target, nuke the build for the target.

Well, at least, there's libelf that's still needed by ltrace, so
we keep it.

     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
    11 predicate for operand1.
