Revert "env: only build env_embedded and envcrc when needed"

Breaks building on many boards, and no really clean fix available yet.

This reverts commit 6dab6add2d8ee80905234b326abc3de11be1d178.

 of environment data (variable area); in general, we support the
 following configurations:
 
-- CONFIG_BUILD_ENVCRC:
-
-	Builds up envcrc with the target environment so that external utils
-	may easily extract it and embed it in final U-Boot images.
-
 - CONFIG_ENV_IS_IN_FLASH:
 
 	Define this if the environment is in flash memory.
