[coreboot] gcc in coreboot

[ali hagigat]

If I want to run gcc, ld , as from elf32-i386 toolchain, should i
change the file .xcompile in the root directory of Coreboot?
and change the following line:
CC:=gcc -Wa,--divide -fno-stack-protector -Wl,--build-id=none
to:
CC:=util/crossgcc/xgcc/i386-elf/bin/gcc -Wa,--divide
-fno-stack-protector -Wl,--build-id=none

Will that be enough? (no need to change the system header files paths?
or other thing?)
Sorry to take up the time of people of the mailing list and thank you
all in advance.
