[PATCH v3] Add support for nanoMIPS architecture

[Nick Clifton]

Hi Aleksandar,

> Add a subset of the functionality required for GDB.

Building the binutils configured as --enable-targets=all --enable-64-bit-bfd
I get a build failure:

   /bin/ld: ../bfd/.libs/libbfd.a(elfxx-nanomips.o): in function `_bfd_elf_mips_mach':
   bfd/elfxx-nanomips.c:227: multiple definition of `_bfd_elf_mips_mach';../bfd/.libs/libbfd.a(elfxx-mips.o):
   bfd/elfxx-mips.c:6918: first defined here

Then there are the problems building readelf:

binutils/readelf.c: In function 'get_machine_name':
binutils/readelf.c:2962:5: error: duplicate case value
  2962 |     case EM_IMG1:               return "Imagination Technologies";

... and more ...

Please could you check and fix these issues ?
