There are definitely systems with python3 and no python. Eg, Debian 12

Some (most?) distros have a tiny package that sets up python to go to
python3.
On Debian, it's python-is-python3, and buildprep installs it.
On Fedora, it's python-unversioned-command-3.13.2
I'll add it to buildprep
On FreeBSD, python311-3.11.11 installs python3 and python3-3_4 sets up a
link so python gets python3. I don't know if it does anything else.
On FreeBSD, ./buildprep -n says:
pkg install bison python3
ln -s /usr/local/bin/python3 /usr/local/bin/python
pkg install ca_root_nss
I think the ln step is bogus. So I'll remove it.
What makes you think it's bogus? Aside from whether it's best to point to
'python3' or the target of 'python3', the 'python' symlink is what one is
supposed to have to allow unversioned shebangs to work (not to mention
users who simply want to type 'python').
buildprep has simpilar code for NetBSD. I'll have to check to see if that
is needed.
