It may be changing with time, too.  Same experiment on Red Hat distros:

gcc 8.5.0 on RHEL8:
$ gcc -Q --help=target | grep march
  -march=                               x86-64
$ gcc -m32 -Q --help=target | grep march
  -march=                               x86-64

gcc 11.5.0 on RHEL9:
$ gcc  -Q --help=target | grep march
  -march=                               x86-64-v2
  Known valid arguments for -march= option:
$ gcc -m32 -Q --help=target | grep march
  -march=                               x86-64
  Known valid arguments for -march= option:

gcc 14.3.1 on Fedora 41:
$ gcc -Q --help=target | grep march
  -march=                               x86-64
  Known valid arguments for -march= option:
$ gcc -m32 -Q --help=target | grep march
  -march=                               i686
  Known valid arguments for -march= option:
