[coreboot] I can not add FILO as a payload

[ali hagigat]

I want to add FILO as a payload. There are some errors.

I got the Coreboot source by :
git clone http://review.coreboot.org/p/coreboot

Then inside the project I had:
/root/bios/coreboot/payloads/libpayload,
/root/bios/coreboot/payloads/filo

I executed the some steps according to the following file:
/root/bios/coreboot/payloads/filo/README

cd payloads/libpayload/
/root/bios/coreboot/payloads/libpayload> make defconfig
/root/bios/coreboot/payloads/libpayload> make
/root/bios/coreboot/payloads/libpayload> make DESTDIR=../filo/build install
/root/bios/coreboot/payloads/libpayload> cd ../filo
/root/bios/coreboot/payloads/filo> make menuconfig
/root/bios/coreboot/payloads/filo> make
Found Libpayload

I am copying the .config files of filo and lipayload:
