[U-Boot-Users] [PATCH] Fix warnings while compiling net/net.c for MPC8610HPCD board

MPC8610HPCD board adds -O2 gcc option to PLATFORM_CPPFLAGS
causing overriding default -Os option. New gcc (ver. 4.2.2)
produces warnings while compiling net/net.c file with -O2
option. The patch is an attempt to fix this.
