binutils-2.16.92 build failures, Linux X PPC, SPARC.

[Don Lindsay <lindsayd at cisco dot com>]

There was an appeal for people to testdrive the 2.17 RC.
So, this is a summary of some successes and failures.

I merged gcc-4.1.0 on top of binutils-2.16.92 on top of newlib-1.14.0,
using cpio.

i686-pc-linux-gnu bootstrapped fine, and a cross to mips64-elf went OK.
But a cross to powerpc-eabi died in <buildarea>/bfd with:

        /bin/sh ./libtool --mode=compile gcc -DHAVE_CONFIG_H -I.
                <etc..> -Wall  <etc..>
                -Werror -g -O2 -c -o coff-rs6000.lo $src/bfd/coff-rs6000.c
        cc1: warnings being treated as errors
        In function 'xcoff_write_archive_contents_old':
                :2086: warning: value computed is not used


I didn't have this problem with binutils-2.16.1. As per the suggestion
in /bfd/ChangeLog-2005, I added --disable-werror to my configure
command. So the next try got further:
	[Condensing <build area> to $b, <install area> to $i, and
	 neatening a bit]

The config.log in question seems to be (from its timestamp)

	$b/powerpc-eabi/libssp/config.log

which has

        configure:2352: error: C compiler cannot create executables


I punted by adding --disable-libssp to my configure command. The linux 
cross powerpc-eabi then succeeded.

I ran the same script on Solaris 8, bootstrapping from a GCC 3.4.3 instead 
of /usr/bin/gcc. The bootstrap failed with:

       /bin/ksh $src/gcc/mkconfig.sh tconfig.h
        ./xgcc -B./ -B$i/sparc-sun-solaris2.8/bin/
        -isystem $i/sparc-sun-solaris2.8/include
        -isystem $i/sparc-sun-solaris2.8/sys-include
        -L$b/gcc/../ld  -c -o crt1.o -x assembler-with-cpp
        $src/gcc/config/sparc/sol2-c1.asm
                ./as: error: $b/gcc/.libs/as-new does not exist
                This script is just a wrapper for as-new.
                See the libtool documentation for more information.

??

Which is as far as I've got. Logs and scripts on request.
