[U-Boot] [PATCH v4 2/5] spl: don't mark __u_boot_cmd* as undefined

[Ilya Yanok]

__u_boot_cmd* symbols are not used in SPL so there is no need
to tell the linker that they are undefined. With these symbols
marked as undefined linker fails to garbage collect some unused
functions and even fails to build the resulting image.
