BUG: CVS sparc builds

[Nathan Sidwell <nathan at acm dot org>]

Hi,
this patch
Tue Nov 23 00:57:10 1999  Rainer Orth  <ro@TechFak.Uni-Bielefeld.DE>

        From Casper H.S. Dik on comp.unix.solaris, 23 Oct 1998:
        * configure.in: Try building a bi-arch 32/64-bit compiler on
        sparc-*-solaris2.7 and higher.
        * configure: Rebuild.

is not right
1) it selects sparc/sol2-sld-64.h (system linker file), ignoring
$gnu_ld (this may be ok, but is at variance with the previous behaviour
which would choose sparc/sol2-sld.h or sparc/sol2.h).
2) assumes the remaining toolchain can build 64bit apps. Here
gnu as has been built without 64 bit support and so barfs on -xarch=v9
