The combination ENV_IS_IN_NVRAM=y, ENV_IS_IN_REMOTE=y fails to build:
env/remote.o:/mnt/ext4/devel/u-boot/env/remote.c:17: multiple definition of `env_ptr' env/nvram.o:/mnt/ext4/devel/u-boot/env/nvram.c:41: first defined here
It's not necessarily a meaningful combination, but for build-testing it's nice to be able to enable most ENV_IS_IN_* at the same time, and since these env_ptr are not declared anywhere, they really have no reason to have external linkage.
nand.c and flash.c similarly already define file-scope static env_ptr variables.
