9.6p1 test suite help

[Jack Hill]

Hi OpenSSH,

I'm working on updating Guix's openssh package definition to the latest 
release. So far, I have only changed the version (and checksum) and left 
the build/test/install recipe the same. However, the test suite now fails. 
I could use some pointers to find out what exactly is going wrong with the 
failing test or how to fix it. I'm happy to provide more information about 
my environment, but I'm not immediately sure what's relevant. Hopefully 
the following is a good starting place.

regress.log looks as follows:

"""

I also see lines like:

"""

Overwrite (y/n)? ssh-keygen for ssh-rsa failed
"""

on the console while the tests are running.

Thanks!
