Currently our coreboot toolchain cannot build the Linux kernel in case of x86_64. It spits out the following error during build: ``` make -C build/kernel-6_3 \ CROSS_COMPILE=/home/max/coreboot-amd/util/crossgcc/xgcc/bin/x86_64-elf- \ ARCH=x86_64 KBUILD_BUILD_USER=coreboot KBUILD_BUILD_HOST=reproducible \ KBUILD_BUILD_TIMESTAMP=Tue Aug 20 13:36:03 2024 KBUILD_BUILD_VERSION=0 bzImage arch/x86/lib/clear_page_64.S: Assembler messages: arch/x86/lib/clear_page_64.S:18: Error: number of operands mismatch for `mov' arch/x86/lib/clear_page_64.S:27: Error: number of operands mismatch for `mov' make[4]: *** [scripts/Makefile.build:374: arch/x86/lib/clear_page_64.o] Error 1 make[3]: *** [scripts/Makefile.build:494: arch/x86/lib] Error 2 make[3]: *** Waiting for unfinished jobs.... arch/x86/entry/entry_64.S: Assembler messages: arch/x86/entry/entry_64.S:437: Error: unbalanced parenthesis in operand 1. arch/x86/entry/entry_64.S:262: Info: macro invoked from here arch/x86/entry/entry_64.S:265: Info: macro invoked from here arch/x86/entry/entry_64.S:439: Error: unbalanced parenthesis in operand 1. arch/x86/entry/entry_64.S:262: Info: macro invoked from here arch/x86/entry/entry_64.S:265: Info: macro invoked from here make[5]: *** [scripts/Makefile.build:374: arch/x86/entry/entry_64.o] Error 1 make[4]: *** [scripts/Makefile.build:494: arch/x86/entry] Error 2 make[4]: *** Waiting for unfinished jobs.... make[3]: *** [scripts/Makefile.build:494: arch/x86] Error 2 make[2]: *** [Makefile:2025: .] Error 2 make[1]: *** [targets/linux.mk:60: build/kernel-6_3/arch/x86/boot/bzImage] Error 2 make: *** [payloads/external/Makefile.mk:401: payloads/external/LinuxBoot/build/Image] Error 2 ``` In order to fix it, we will default to the host toolchain in order to build x86_64 Linux. For that we add another Kconfig that decides, whether or not a cross toolchain is used to build Linux.
