[PATCH v2] pango: don't try to split modules if none were installed

[Phil Blundell <philb@gnu.org>]

If pango is configured --with-included-modules then the modules
directory may not exist.  Trying to call do_split_modules() on a
nonexistent path leads to python stack traceback spew and a build
failure, so check in advance whether that directory is present before
trying to do any splitting.
