scripts: add option to strip all toolchain executables

To reduce filesizes of the toolchain and even improve build times
of projects to be build with this toolchain it is usefull to strip
the delivered toolchain executables. Since it is not likely that we
will debug the toolchain executables itself we do not need the
debug information inside the executables itself.

     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.
