in linux-next, the libxxhash-dev package is required for x86_64 to build properly with CONFIG_LIVEPATCH=y (which is most major distributions).
error: objtool: --checksum not supported; install xxhash-devel/libxxhash-dev and recompile

Research direction
No TuxMake file or test is named. Start by tracing the Linux kernel build setup for x86_64 with CONFIG_LIVEPATCH=y and inspect how required host packages are declared or checked. Done means this configuration no longer fails because libxxhash-dev is missing.
