Maciej W. Rozycki 78da84f994 MIPS/LD/testsuite: Correct mips-elf.exp test ABI/emul/endian arrangement
Similarly to commit 86b24e15c4 ("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.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
