Bug#841500: gcc-6: Unable to compile upstream kernel with previous .config

[Eric Valette <eric2.valette@orange.com>]

Package: gcc-6
Version: 6.2.0-9
Severity: grave
Justification: renders package unusable

Wanted to patch my upstream kernel for the COW vulenraibilty. Applied
incremental patch, started the rebuild with same .config:
