[distcc] remote compilation fails

[Christer Solskogen]

but locally is no problem!

I have setup a Pi400 with Ubuntu and a KVM on x86_64 with Ubuntu. Both 
are running Ubuntu 20.10. The x86_64 is the fast machine, so I use that 
the client and the Pi as the master.

But compilation fails with when using distcc. At least on the project 
I'm trying to compile. The funny thing is that I can compile it on both 
machines locally, but NOT when using distcc.
