[PATCH] [ARM] Update knowledge of bfd architectures

[Thomas Preudhomme <thomas dot preudhomme at linaro dot org>]

Hi,

Commit c0c468d562649df0f695737262b6230b7a56a4bb updated bfd's knowledge
of Arm architectures to Armv5TEJ and later but missed a couple of
locations. Missing one that this patch cover are:

- processor list in bfd/cpu-arm.c used by objdump to select a CPU to
  disassemble for
- architecture lists for .note.gnu.arm.ident notes used by GAS
  (bfd_arm_update_notes ()) and objcopy (architectures array used by
  bfd_arm_get_mach_from_notes ())
- architectures to set bfd mach to in GAS' md_begin ()

Note that the CPU list in bfd/cpu-arm.c was simply copied over from
GAS' CPU list but sorted alphabetically as already done for existing
entries. When working on this I've noticed that none of the existing
testcase in the whole binutils covered the note codepaths so I've added
testcases even for already present architectures. I've only ever managed
for bfd_arm_get_mach_from_notes () to have an effect by using objcopy on
a file with a note but no Arm build attribute. I thus make use of both
objcopy supported by run_dump_test which requires to have an ld line as
well. This is now possible with the separate patch posted to fix ld
action in run_dump_test.

ChangeLog entries are as follows:

Testing: No testsuite regression when targeting arm-none-eabi.

Is this ok for master?
