We document in gdb/README the minimum supported version, so I think you
could drop the "Python 3" reference completely if you wanted.

Speaking of which, said gdb/README note should also be updated, as is documents
that the oldest supported version is 2.6:

`--with-python[=PYTHON]'
     Build GDB with Python scripting support.  (Done by default if
     libpython is present and found at configure time.)  Python makes
     GDB scripting much more powerful than the restricted CLI
     scripting language.  If your host does not have Python installed,
     you can find it on `http://www.python.org/download/'.  The oldest
     version of Python supported by GDB is 2.6.  The optional argument
     PYTHON is used to find the Python headers and libraries.  It can
     be either the name of a Python executable, or the name of the
     directory in which Python is installed.
