It means to compile binaries which only run on the machine it is compiled on. (-mtune=native would be more tolerable, but still doesn't make sense, why would you want to tune based on what the builder happens to be?) The package needs fixing to use sane compiler flags (ideally our RPM_OPT_FLAGS, if Clang can grok those, otherwise an as large subset of them as possible, but no bogus extra flags such as -march=native, and -O3 is also usually frowned upon).
