Hi Martin,

i see the same also on Ubuntu 18.04. Samba 4.10 has the same problem,
Samba 4.9 compiles. 4.10 started using Python3 for the build. Then i
came across this comment from metze, that there might be a problem with
parsing the output of krb5-config with Python3:

commit 8061983d4882f3ba3f12da71443b035d7b672eec
Author: Stefan Metzmacher <metze at samba.org>

    wscript: separate embedded_heimdal from system_heimdal
    
    This allows to default (embedded_heimdal) to build even with a
    broken krb5-config file from Heimdal.
    
    In the system_heimdal case we parse the content of krb5-config
    instead of just executing it. This fails on FreeBSD 12 as
    krb5-config contains iso-8859-1 characters, which can't be parsed
    as unicode python buffers when using python3.
    
    Fixing the system_heimdal case is a task for another day,
    I guess it will only work once we imported a current heimdal version
    and actually tested the system_heimdal case.

I am not sure if that is the exact problem, but it would seem worthwhile
to look closer in that area.
