[U-Boot] [PATCH] ARM: Fix building without CONFIG_CMD_NET

[Marcel Ziswiler <marcel@ziswiler.com>]

Delta and Zylonite both do not define CONFIG_CMD_NET by default and therefore
failed building:

lib_arm/libarm.a(board.o): In function `start_armboot':
/home/sumo/Noser/Linux/u-boot.git/lib_arm/board.c:360: undefined reference to `getenv_IPaddr'
make: *** [u-boot] Error 1

Saw that this got already fixed for ppc. Duno why nobody considered ARM as well!
