I don't think this is a good idea. Target-specific code should not be
required to correctly handle jumbo pointers, e.g. in "(gdb) print
foo ($_)". In a command function, we must already have some idea of
what the associated architecture is (e.g. to initialize the
architecture used by the expression evaluator); why not use that?
