I suppose you mean the attached patch... the problem is that even if
using that patch I still get:
mipsel-linux-gcc -Wa,-gstabs -D__ASSEMBLY__ -g -Os -D__KERNEL__ -DTEXT_BASE=0xbfc00000 -I/home/giometti/Projects/exadron/wwpc/uboot-mips-exadron/include -fno-builtin -ffreestanding -nostdinc -isystem /usr/local/mipsel/lib/gcc/mipsel-linux/3.4.3/include -pipe -DCONFIG_MIPS -D__MIPS__ -march=4kc -mtune=4kc -mabicalls -c -o cpu/mips/start.o /home/giometti/Projects/exadron/wwpc/uboot-mips-exadron/cpu/mips/start.S
