I don't beleive that is always the case:
$ m68k-linux-gcc -m68000 -dM -E - < /dev/null | grep 68020
$ m68k-linux-gcc -m5200 -dM -E - < /dev/null | grep 68020
$ m68k-linux-gcc -dM -E - < /dev/null | grep 68020
#define __mc68020__ 1
#define __mc68020 1
#define mc68020 1
$ m68k-linux-gcc -mcpu32 -dM -E - < /dev/null | grep 68020
#define __mc68020__ 1
#define __mc68020 1
#define mc68020 1
$ m68k-linux-gcc --version
