    Update libffi to 3.2.1
    
    Libffi currently fails to build on master
    (https://github.com/atgreen/libffi/issues/150). I recommend overriding
    the tag in your .jhbuildrc-custom:
    
    branches['libffi'] = (None, 'v3.2.1')
    
    However, this isn't hardcoded into the modules file.

 <!-- This is the latest 0.10 version. Later versions are 1.29 and intended to work with glib 2.29; the minor 
version of gobject-introspection will track the minor version of glib that it's intended to work with. Note 
that in the unlikely event you need to introspect Gtk+-2.0, you need to build Glib 1.28 and use this 
gobject-introspection. The default is to *not* introspect Gtk+-2.0 and to use the latest GLib and 
Gobject-Introspection with Gtk3 -->
