Source: nwchem Version: 6.6+r27746-2 Severity: grave src/config/makefile{,-legacy}.h sets -march=native and -mtune=native in amd64 builds.
-march=native means the code will only run on machines with a CPU compatible with the one on the machine where the package was built. Building on a different buildd machine can also change where the code can run - including breaking existing setups in stable updates. -mtune=native is less fatal, but in addition to (rare) problems due to the fact that the program is compiled differently depending on the build machine it makes the build non-reproducible. Please remove -march=native and -mtune=native
