  python: use Python's sys.prefix and sys.exec_prefix
  
  for PYTHON_PREFIX and PYTHON_EXEC_PREFIX; new configure options
  --with-python_prefix and --with-python_exec_prefix to set explicitly.
  
  This change fixes https://bugs.gnu.org/35322.
  
  * m4/python.m4 (AM_PATH_PYTHON): use Python's sys.prefix and
  sys.exec_prefix for PYTHON_PREFIX and PYTHON_EXEC_PREFIX,
  instead of $prefix and $exec_prefix. But use a variable
  reference to ${prefix} if it is contained within sys.prefix;
  similarly for exec_prefix. Also support new configure options
  to set explicitly.
  (PYTHON_PREFIX, PYTHON_EXEC_PREFIX): AC_SUBST these.
  (am_cv_python_pythondir): use our new $am_cv_python_prefix,
  substituting ${PYTHON_PREFIX}.
  (am_cv_python_pyexecdir): likewise.
  * doc/automake.texi (Python): PYTHON_PREFIX, PYTHON_EXEC_PREFIX,
  document new approach.
  * t/instmany-python.sh: set PYTHON_PREFIX as needed.
  * t/python-vars.sh (PYTHON_EXEC_PREFIX, PYTHON_PREFIX): also set from
  Python's sys.{exec_,}prefix; use ${PYTHON_{EXEC,}PREFIX} instead
  of ${exec_,}prefix.
