Build the lwIP library when NET_LWIP is enabled. The following files are adaptation layers written specially for U-Boot:
lib/lwip/u-boot/arch/cc.h lib/lwip/u-boot/arch/sys_arch.h (empty) lib/lwip/u-boot/limits.h (empty) lib/lwip/u-boot/lwipopts.h
They were initially contributed by Maxim in a previous RFC patch series.
