fonts/fontforge build failure

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

Hi,

The latest fonts/fontforge package fails to build due to a python
extensions script being ran with python2.7 instead of python3.7 or
later:
...


                 Exception occurred:

Please also report this if it was a user error, so that a better error

Any advice? My PYTHON_VERSION_DEFAULT is 3.7, although there are a
number of packages built for 2.7 and 3.8.
