[PATCH 15/31] hw/core/cpu: Return static value with gdb_arch_name()

From: Akihiko Odaki <akihiko.odaki(a)daynix.com&gt; All implementations of gdb_arch_name() returns dynamic duplicates of static strings. It's also unlikely that there will be an implementation of gdb_arch_name() that returns a truly dynamic value due to the nature of the function returning a well-known identifiers. Qualify the value gdb_arch_name() with const and make all of its implementations return static strings.
