Empty configuration file yields warnings in startup messages

[PoC-dev]

When starting Hercules with an empty configuration file, I think these warning messages should not happen:

12:37:09 HHC00811I Processor CP00: architecture mode z/Arch
12:37:09 HHC02385W CPUMODEL 0586 does not technically support TXF
12:37:09 HHC00007I Previous message from function 'txf_model_warning' at transact.c(2562)

and

12:37:09 HHC17736W TXF: TIMERINT 50 is too small; using default of 400 instead
12:37:09 HHC00007I Previous message from function 'txf_set_timerint' at transact.c(2587)

Full log: startup.txt

Mainly a cosmetic issue, IMHO.

When starting Hercules with an empty configuration file, I think these warning messages should not happen:

Why not?

The default architecture mode if not specified is z/Arch, and the default setting for the TXF facility is enabled, and the default cpu model is 586. Thus from Hercules's point of view the warnings are completely justified.
