> it would fix the build

Patch set 11 (reverting removed hunk, and replacing spaces by comma) fixed the GCC build issues. (clang build issue still remains.)

Patchset:

PS11: 
Using clang it fails with:

/usr/bin/ld: relocatable linking with relocations from format elf32-i386 (/cb-build/coreboot-gerrit.0/clang/AMD_GARDENIA/smm/mainboard/amd/gardenia/static.o) to format elf64-x86-64 (/cb-build/coreboot-gerrit.0/clang/AMD_GARDENIA/smm/smm.o) is not supported
    clang-15: error: linker command failed with exit code 1 (use -v to see invocation)
    make[2]: *** [src/cpu/x86/smm/Makefile.inc:18: /cb-build/coreboot-gerrit.0/clang/AMD_GARDENIA/smm/smm.o] Error 1

Arthur suggested to add something like `-march=i386` to the cflags.
