3abf975826 MIPS/binutils/testsuite: Correct mips.exp test ABI/emul/endian arrangement
The binutils testsuite supports involving LD in processing test cases
and with the MIPS target that has the same issues the LD testsuite does.

So to support LD in the MIPS part of the binutils testsuite similarly
to commit 86b24e15c4 ("MIPS/LD/testsuite: Correct comm-data.exp test
ABI/emul/endian arrangement") update the mips.exp test script to:

- correctly select emulations for targets using non-traditional MIPS
  emulations,

- correctly select ABIs for targets that do not support all of them,

- use the default endianness selection where possible to benefit targets
  that support only one,

- simplify test invocation by providing ABI-specific `run_dump_test'
  wrappers, specifically `run_dump_test_o32', `run_dump_test_n32' and
  `run_dump_test_n64', which remove the need to use conditionals across
  the Expect script or to repeat ABI-specific GAS and LD flags with each
  invocation,

borrowing changes from commit 78da84f994 ("MIPS/LD/testsuite: Correct
mips-elf.exp test ABI/emul/endian arrangement").

As a side effect this disables o32 ABI testing for targets that are not
supposed to support them and do not with LD, but still have such support
with BFD and GAS due to our inflexibility in configuration.  Ultimately
we ought to support having o32 completely disabled.

e5713223cb MIPS/BFD: For n64 hold the number of internal relocs in `->reloc_count'
Revert parts of commit fee24f1c5b ("objdump improvements for mips
elf64"), <https://sourceware.org/ml/binutils/2003-03/msg00108.html>, and
make the `->reloc_count' member of `struct bfd_section' hold the actual
number of internal relocations stored in its `->relocation' vector.  To
do so adjust `mips_elf64_slurp_one_reloc_table' to set `->reloc_count'
to the actual number of internal relocations retrieved and discard
`mips_elf64_canonicalize_reloc', `mips_elf64_canonicalize_dynamic_reloc'
and their corresponding target macros.  Contrary to the description of
`mips_elf64_slurp_one_reloc_table', adjusted appropriately, this makes
generic relocation processing code happy and satisfies the "merge notes
section" binutils test case.

Add extra binutils test cases to expand the coverage of the generic
"merge notes section" test case, now passing with the n64 ABI, across
the MIPS o32, n32 and n64 ABIs regardless of the default ABI selected in
target configuration, and also to verify correctness of the relocations
produced.  Conversely, do not provide any additional test cases for the
original issue addressed with the commit referred:

- objdump would display only 1/3 of the total number of relocations,
  because it used the external relocation count, but each external
  relocation is brought in as 3 internal relocations.

as n64 ABI relocation processing with `objdump -r' and `objdump -R' is
already widely covered across the GAS and LD test suites.
