(the second time is for bfd's default architecture)

Yep, ok!  There is no longer a need to do this, and other similar, 
calls.  Will make understanding things a little bit easier.

Thanks for testing this on non-multi-arch as well.

This change got me thinking again about your other post about 
initialization order and a race condition.

You're right, there is one.  All the gdbtype info needs to be created 
before anything else vis:

	o	create base architecture
	o	create gdbtypes from architecture
	o	initialize everything else (like regcache).

otherwize, as you were seeing with regcache, there isn't that guarentee 
that the type info is available.

enjoy,
Andrew
