Bug#841420: --enable-default-pie breaks kernel builds

[S R Wright <srw6666@gmail.com>]

Concurring with Wolfgang;  pulling the source straight from kernel.org 
and using identical .config files will work with 6.2.0-6 but fail with 
6.2.0-7.   I was able to build and install 4.8.3 with no issues after 
back-revving gcc et. al. to 6.2.0-6
