[RFA] regcache fix

["Martin M. Hunt" <hunt@redhat.com>]

Currently build_regcache is called 3 times, once at initialization, 
before any architectures are registered, once when the host is 
registered and once when the target is registered.  I don't see 
any reason for the first call, and in some non-multiarched 
targets it can cause core dumps.

	* regcache.c (_initialize_regcache): No need to call
	build_regcache() at this time; it gets called whenever
	the gdbarch changes.
