jonathan fe7810c7dc egcs-1.1 netbsd/mips config fixes:
1. Change linkspec to not pass -nostdlib to binutils ld, since on mips,
      ld parses "-nostdlib" as a set of short options which produce
      nonworking binaries.
  2.  Turn off ASM_OUTPUT_DEF definition: the egcs iris6.h says that
      our old definition (from gcc 2.7.2.2 iris5.h isnt really whats
      wanted here.
  3.  Turn off SET_ASM_OP (which defaults to .set) to stop
      dwarf2out.c from emitting debug(?) info for C++ using ".set",
      since both gas and mips as use .set to control assembler
      optimizations, not for equating labels. From iris6.h.
      and nonzero -G values are incompatible with PIC.
  4.  Set default GVALUE (for -G) to 0; this target always produces PIC
      by default, and on mips, PIC is incompatible with `small' segment.
  5.  Set TARGET_DEFAULT to enable "-mdebuga" to defeat
      GO_IF_LEGITIMATE_ADDRESS "smarts". GO_IF_LEGITIMATE_ADDRESS pretends
      that mips supports an address mode of constant + register.
      For constants larger than 16 bits, that relies on assembler fixups
      via $at.  egcs 1.1 (expr.c delta 1.76) may break up those addresses
      such that the backend cannot output them as offsets in load or store
      instructions anymore; no other patterns match so egcs coredumps.

src/gnu/README:			<$Revision: 1.3 $>


Organization of Sources:

This directory hierarchy is using a new organization that
separates the GNU sources from the BSD-style infrastructure
used to build the GNU sources.  The GNU sources are kept in
the standard GNU source tree layout under:

	dist/*

The build infrastructure uses the normal BSD way under:

	lib/*
	usr.bin/*

The makefiles in the above hierarchy will "reach over" into
the GNU sources (src/gnu/dist) for everything they need.


Maintenance Strategy:

The sources under src/gnu/dist are generally a combination of
some published distribution plus changes that we submit to the
maintainers and that are not yet published by them.  There are
a few files that are never expected to be submitted to the FSF,
(i.e. BSD-style makefiles and such) and those generally should
stay in src/gnu/lib or src/gnu/usr.bin (the BSD build areas).

Make sure all changes made to the GNU sources are submitted to
the appropriate maintainer, but only after coordinating with the
NetBSD maintainers by sending your proposed submission to the
<tech-toolchain@netbsd.org> mailing list.  Only send the changes
to the third-party maintainers after consensus has been reached.


Maintenance History:

Original GNU sources were imported as follows:	[gwr,1997/09/24]
	dist/gdb	FSF gdb-4-16
	dist/readline	FSF readline-2-1
	dist/(other)	FSF binutils-2-8
Updated dist/(other) to FSF binutils-2-8-1	[gwr,1997/09/24]

Several changes have been integrated since the initial import,
and those will be submitted to the maintainers after this code
has been tested on all NetBSD ports (i.e. after NetBSD 1.3).
Some of the integration was done by importing a file from a
later snapshot.  Please log all such imports here.

Updated these files via import with tags: FSF cygnus970817
