Hello,

The following patch is causing trouble on sparc-solaris:

> 2009-07-08  Hui Zhu  <teawater@gmail.com>

> 	* solib.c (solib_bfd_open): Output a warning if solib's
> 	architecture is not compatible with inferior's architecture.

I now see:

    (gdb) run
    Starting program: /[...]/sparc64/ex/task_switch 
    warning: `/usr/platform/SUNW,Sun-Fire-V440/lib/sparcv9/libc_psr.so.1': Shared library architecture sparc:v9a is not compatible with target architecture sparc:v9.

> +  if (b->compatible (b, bfd_get_arch_info (abfd)) != b)

In my case, b->compatible is bfd_default_compatible. the architecture
is set to sparc:v9, and the shared library's architecture is sparc:v9a.
The problem is that b->compatible is returning the architecture that
is "more featureful" of the two, which in this case is sparc:v9a.
As a result, we emit the warning.

Looks to me like the check is too aggressive and should be changed
to == 0. Would that be correct?

        * solib.c (solib_bfd_open): Relax a bit the compatibility check.

Tested on sparc64-solaris.
