Subject: Failure to distribute distcc jobs compiling kernel versions >=5.2.0

Compiling the kernel using distcc since version 5.1.16 works but
versions >=5.2.0 fail to distribute jobs. This is true compiling
5.4-rc2.  Whatever is causing this breakage, it has not been
backported to the 4.19-lts series. I can build 4.19.78 with distcc
working just fine.

distcc v3.3.3
gcc v9.2.0

I am not subscribed so please CC my personal email address with any replies.

Example compiling a recent kernel on the distcc client:
