That makes sense.

From the show functions, which are called by the CLI infrastructure, I
think you're supposed to use get_current_arch (in arch-utils.h).

From other functions, mostly, you need the caller to pass an
architecture.  An increasing portion of GDB is parameterized
this way.  That'll work for e.g. target_wide_charset ().

I don't think you can do either from _initialize_charset.  That may
have to happen lazily...
