coreboot's toolchain is only used to build "target" code, i.e. the
coreboot itself. There are some tools to be compiled for the host,
however, during the build process. As we usually only build a cross
compiler, the original host toolchain will always be used for the
tools.

It's most likely the build of such a tool that fails. If you can
update your host toolchain, that's probably the best thing to do.

Hi David,

Thanks for the response.
I did check the option and its not enabled for me.

Additional Info :
I was very well able to build the crossgcc-i386 and can see that
coreboot/util/crossgcc/xgcc/bin $ ./i386-elf-gcc --version
i386-elf-gcc (coreboot toolchain vf5fa96f9c3 2019-09-21) 8.3.0

Bu when I do "make" from the root of coreboot, the build fails for me because 
the host gcc version is 4.8.5. If I update the host gcc version to gcc-8, the 
build passes for me. This somewhat indicates that coreboot build system still 
picks the host toolchain, and not the coreboot's internal toolchain.

Do I need to export some env variable before calling make, say CROSS_COMPILE or 
something similar to point to the coreboot's internal toolchain?

Regards,
Naveen

Hi Naveen,
Do you have the ANY_TOOLCHAIN option enabled? It's under General setup --> 
Allow building with any toolchain.

Make sure that option is not selected if you want to use coreboot's crossgcc 
toolchain.

Looks like coreboot build system still uses the host gcc. How can I make with 
coreboot toolchain, instead of the host gcc toolchain.
