[v3,02/12] net-lwip: build lwIP

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.
