Subject: bug#38464: python-hy REPL is unusable

1. install python-hy
2. run hy3 (to make sure it's setup to use python 3.7.4)
3. press <return> with or without typing anything.
It prints the following error at the end of a long stack trace:

ImportError: invalid flags 1495674643 in 'hy.core.language'

This also happens when using hy2py3, and I have attached a sample stack
trace from hy2py3.

If python2-hy is installed (configured to use the python 2.7, which is
appraching end-of-life), the hy2 REPL and hy2py2 work just fine.

- Does hy fail similarly on other systems, or is this a guix problem?
- If this is a guix issue, what is the best way to fix it?
