From: David Hildenbrand <d...@linux.vnet.ibm.com> This patch provides the name of the architecture in the target.xml if available.
This allows the remote gdb to detect the target architecture on its own - so there is no need to specify it manually (e.g. if gdb is started without a binary) using "set arch *arch_name*". The name of the architecture has been added to all archs that provide a target.xml (by supplying a gdb_core_xml_file) and have a unique architecture name in gdb's feature xml files.
