PS8, Line 1: # NOTE: remove to test _LP64 issue: CONFIG_LP_ARCH_X86_64=y
> What is that first line ?

If CONFIG_LP_ARCH_X86_64=y is included, we will run into the issue shown in https://qa.coreboot.org/job/coreboot-gerrit/263710/. We need help from the community for this build conflict issue in 3rdparty/cmocka and it builds payloads/libpayload/tests/mocks/, where the error is located.
