build error on sparc solaris 2.7, with GNU ld and GNU as

[Mike Stump <mrs at windriver dot com>]

I've not been able to compile on sparc for a while (see testsuite
result reports, if you need to know exctly when).  I'm configuring
with:

../gcc/configure --with-gcc-version-trigger=/kankakee1/tmp/mrs/net/gcc/gcc/version.c --host=sparc-sun-solaris2.7 --prefix=/folk/mrs/packages/gcc-20001113 --with-as=/folk/mrs/bin-27/as --with-ld=/folk/mrs/bin-27/ld --with-gnu-as --with-gnu-ld --norecursion 

And here is the tail of where it dies.  It was a -j5 build, so don't
be confused by ordering.

/bin/sh ../libtool --mode=compile /kankakee1/tmp/mrs/net/gcc-sol/gcc/xgcc -B/kankakee1/tmp/mrs/net/gcc-sol/gcc/ -B/folk/mrs/packages/gcc-20001113/sparc-sun-solaris2.7/bin/ -B/folk/mrs/packages/gcc-20001113/sparc-sun-solaris2.7/lib/ -isystem /folk/mrs/packages/gcc-20001113/sparc-sun-solaris2.7/include -DHAVE_CONFIG_H -I. -I../../../../gcc/libstdc++-v3/libio -I.. -nostdinc++         -I../include -I../../../../gcc/libstdc++-v3/include     -I../libio -I../../../../gcc/libstdc++-v3/libio            -D_GNU_SOURCE -g  -g -O2 -c ../../../../gcc/libstdc++-v3/libio/genops.c

Real problem, or am I being hit by the stick of stupidity?  I've done
a few linux builds from the same exact sources, so, I know they are
sane in an least one respect.
