env: fix cmd_env_sub fct pointers if CONFIG_RELOC_FIXUP_WORKS is not defined

commit ea882baf9c17cd142c99e3ff640d3ab01daa5cec introduces
a command_sub_table for the "env" command. On arm, avr32, m68k,
mips and sparc architectures, relocation needs manual fixups,
so add these fixups for this sub command table too.

Tested on arm/qong board.
          mips board (Ben NanoNote) from Xiangfu Liu
          arm/AT91 board from Reinhard Meyer
