as,nm,ar segfaulting while building libgcc

[Phil Edwards <pedwards at disaster dot jaj dot com>]

I'm using current CVS binutils+gcc in a unified tree.  (Yah, Mr. Bleeding
Edge am I...)  Doing a build of gcc on sparc-sun-solaris2.8 causes a number
of coredumps, all from the freshly-built binutils, all SEGVs:

Dunno why ar gets built as 'ar' instead of 'ar-new'.

Since the build only dies once, I suspect that maybe some of those
happened during configure tests.  There are config.log's scattered all
over the build dir, but I'll try to grep through those later.  The build
gets as far as gluing together libgcc.a:

    /tec/build/3test/binutils/ar  rc ./libgcc.a libgcc/./_muldi3.o
    libgcc/./_divdi3.o libgcc/./_moddi3.o
[...boatloads of .o's, we all know what they look like...]
    libgcc/./__main.o libgcc/./_exit.o libgcc/./_ctors.o libgcc/./_eh.o
    libgcc/./frame-dwarf2.o
    gmake[2]: *** [libgcc.a] Segmentation Fault (core dumped)
    gmake[2]: Leaving directory `/tec/build/3test/gcc'
    gmake[1]: *** [libgcc.a] Error 2
    gmake[1]: Leaving directory `/tec/build/3test/gcc'
    gmake: *** [all-gcc] Error 2

Worked just fine a couple days ago.
