env: remove callback.o for an SPL build
env.h says this about about callback declarations (U_BOOT_ENV_CALLBACK):
* For SPL these are silently dropped to reduce code size, since environment
* callbacks are not supported with SPL.
So env_callback_init() does a lot of work to not find anything in the
guaranteed empty env_clbk list. Drop callback.o entirely from the link
and stub out the only public function defined in callback.o. This cuts
about 600 bytes from the SPL on my ppc build.
