Hi,

In cross-compile remote debug environment, the gdb will load the solib
of local host if user doesn't set sysroot or something.
Load the wrong lib will make gdb get error.

So I make a patch check the solib bfd arch after load it.  I am not
check the other thing in arch_info because the mach of solib and
inferior is not same (powerpc) sometime.

This patch is tested in a i386 ubuntu and powerpc linux.

Thanks,
Hui
