Comment:

 Sorry, but this will totally break C compilers which do not support
 {{{-march=native}}}:

 {{{
     case "`uname -m`" in
         i[3456]86|i86pc|x86_64|amd64)
             # Only add it if CFLAGS do not already contain similar:
             if ! (echo "$CFLAGS" | egrep -- '-march=|-mcpu=|-mtune='
 >/dev/null);
             then
                 CFLAGS="-march=native $CFLAGS"
             fi;;
     esac
 }}}
