It seems that the exact behavior of -Wsign-compare changes between GCC
versions... some of them like the commonlib/lz4_wrapper.c code, and some
don't. Since we don't have a well-defined HOSTCC toolchain this slipped
through pre-commit testing. Explicitly silence the warning to ensure
cbfstool still builds on all systems.
