PR toolchain/45576 at a very small run-time cost.
This was suggested by Richard Earnshaw.
A real fix is known to be in gcc 4.5.3 (as in NetBSD-current) and in
gcc-current; don't apply in that tree.

change, we should be fully conformant with the N32 and N64 ABIs.
Add {fpclassify,infinity,isnan,ininf,signbit}l_ieee754.c back to lib/libc/gen.
Note that infinityl_ieee754.c will work with either 64-bit, 80-bit, or
128-bit long doubles.
local definitions of
ASM_PREFERRED_EH_DATA_FORMAT
ASM_MAYBE_OUTPUT_ENCODED_ADDR_RTX
and make it obvious we're not using local ASM_OUTPUT_INTERNAL_LABEL
This fixes the current build problems (and probably more)
codegen.

* config/m68k/m68k.c (output_move_himode)
config/m68k/m68k.md: remove jump table recognition
* config/m68k/m68k.c (ASM_OUTPUT_CASE_FETCH): use simple pc
relative addressing
Approved by Christos Zoulas, Alistair Crooks and Matthew Green.
The patch was suggested by Gunther Nikl <gnikl@baltic.net> and is part
of gcc 4.3.x.

libgcc/multilib on amd64
- enable the 32/64 bit libgcc/multilib support on sparc64
- adapt mknative-gcc to grab multilib.h
- use --enable-multilib on amd64 and sparc64
none of this affects the installed tools yet, just the src/tools one.

move the AC_CACHE_CHECK(__stack_chk_fail, [ ... ]) code out
of the linux-specific section, so that it will be used by
everyone.
use AC_CHECK_FUNS() to check for __stack_chk_guard on netbsd.
now this test is properly cross-compile friendly.

it may have been set globaly before for NETBSD_ENABLE_PTHREADS.
This caused wrong (old, pre NetBSD 2.0) builtin specs for m68k.

Fixes "internal compiler error: in do_SUBST" on compiling
floating point ops with -msoft-float or -m68010 on LP64 hosts,
and may also close PR toolchain/38359. Tested on alpha.
