Subject: cpu: Introduce CPUClass::gdb_core_xml_file for GDB_CORE_XML
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Replace the GDB_CORE_XML define in gdbstub.c with a CPUClass field.
Use first_cpu for qSupported and qXfer:features:read: for now.
Add a stub for xml_builtin.
