scripts: create the makeinfo wrapper before we set PATH

If we set PATH to the tools wrappers before we create the
makeinfo wrapper, then we may well wrap an existing wrapper
from a previous run.

     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.
