Patch: Switch Linux/mips to stabs

Patch: Switch Linux/mips to stabs

[H . J . Lu]

Based on the recommendations from Ian and Daniel, I checked in the
following patches to switch Linux/mips to stabs.

Thanks.

 Is it really needed to remove ecoff-littlemips and ecoff-bigmips targets
from the list of default ones for MIPS/Linux?  COFF is the format used by
the firmware of certain MIPS-based machines for network-booting, certainly
by DECstations and I'm told that older SGI workstations use this format,
too.  While the elf2ecoff tool as bundled with the kernel seem to be
sufficient to prepare a suitable COFF image, it's grossly limited in
functionality and was added only as a workaround to bugs in binutils.

Sorry. I put it back.

	* config.bfd: Put back ecoff for Linux/mips. Firmwares on some
	MIPS-based machines need it.
