This is the method used in qscintilla2's configure.py (which upstream has generally endorsed):

#! /usr/bin/python

import sys
import os

if sys.platform == 'win32':
    data_dir = sys.prefix
else:
    data_dir = sys.prefix + '/share'

py_sip_dir = os.path.join(data_dir, 'sip')

# Note: Set this by hand since the logic to figure out if we're using PyQt4 or
# PyQt5 isn't relevant to the question (QScintilla does do this, but it's not
# germane).
pyqt = 'PyQt4'

if pyqt is not None:
    pyqt_sip_dir = os.path.join(py_sip_dir, pyqt)
else:
    pyqt_sip_dir = None

print(pyqt_sip_dir)
# prints /usr/share/sip/PyQt4

We should use something similar.
