MIPS/LD/testsuite: Correct mips-elf.exp test ABI/emul/endian arrangement
Similarly to commit 86b24e15c45b ("MIPS/LD/testsuite: Correct
comm-data.exp test ABI/emul/endian arrangement") update the mips-elf.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',
`run_dump_test_n64' and `run_dump_test_eabi', which remove the need to
use conditionals across the Expect script or to repeat ABI-specific
GAS and LD flags with each invocation,
removing numerous test failures for `mips-sgi-irix6', `mips64-openbsd',
`mips64el-openbsd' and `mips64el-ps2-elf' targets and broadening
coverage for several MIPS targets.
There are some new failures for the `mips64el-ps2-elf' target with tests
that were not previously run for that target:
FAIL: MIPS16 link branch to absolute expression (n32)
FAIL: MIPS16 link branch to absolute expression 1 (n32)
FAIL: MIPS16 link branch to absolute expression 2 (n32)
FAIL: microMIPS link branch to absolute expression (n32)
FAIL: MIPS ELF got reloc n32
FAIL: MIPS ELF xgot reloc n32
FAIL: undefined weak symbol overflow (n32)
FAIL: R_MIPS16_HI16 and R_MIPS16_LO16 relocs n32
FAIL: ld-mips-elf/attr-gnu-4-0-n32-ph
FAIL: ld-mips-elf/attr-gnu-4-1-n32-ph
FAIL: ld-mips-elf/attr-gnu-4-2-n32-ph
FAIL: ld-mips-elf/attr-gnu-4-3-n32-ph
FAIL: MIPSr6 JALR reloc unaligned/cross-mode link test (n32)
which are mostly due to dump discrepancies caused by mapping differences
coming from the default linker scripts used by these test cases, or
sometimes because of the specific MIPS processor architecture recorded
in the ELF file taking precedence over the general MIPS ISA level also
recorded. Finally, the R_MIPS16_HI16/R_MIPS16_LO16 relocation test
failure is a preexisting issue with the IRIX style emulation.
These failures will have to be addressed separately.

(run_dump_test_o32, run_dump_test_n32, run_dump_test_n64)
(run_dump_test_eabi): New procedures.
(has_newabi, has_elf32): Remove variables.
(has_abi): New associative array variable.
(abi_asflags, abi_ldflags): Update settings across targets.
(irixemul): New variable.
Replace `run_dump_test' calls where applicable throughout with
`run_dump_test_o32', `run_dump_test_n32', `run_dump_test_n64'
and `run_dump_test_eabi' as appropriate. Remove explicit
passing of `abi_asflags' and `abi_ldflags'. Use `noarch' for
tests that require their own architecture setting. Force the
big endianness for tests that require it. Select the endianness
required for `objdump invocation with the `reloc-2' test.
Conditionalize tests run via `run_ld_link_tests' on the ABI
required and use the ABI list from the `has_abi' array where
appropriate.

ELF dynsyms
Many ELF targets arrange to emit a number of section symbols in
.dynsym for use by dynamic relocations. This happens before the
dynamic relocations are output, and the need for those symbols
determined. In most cases they are not needed. A proper analysis of
the need for dynamic section symbols is target specific and tedious,
so this patch just excludes them in the obvious case when no

ELF dynsyms
Many ELF targets arrange to emit a number of section symbols in
.dynsym for use by dynamic relocations. This happens before the
dynamic relocations are output, and the need for those symbols
determined. In most cases they are not needed. A proper analysis of
the need for dynamic section symbols is target specific and tedious,
so this patch just excludes them in the obvious case when no
dynamic relocations are present.
The patch also runs the new pr23161 and pr23162 tests on more targets.
