4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
commit 90944e40ba1838de4b2a9290cf273f9d76bd3bdd upstream.
If the gcc is configured to do -fPIE by default then the build aborts later with: | Unsupported relocation type: unknown type rel type name (29)
Tagging it stable so it is possible to compile recent stable kernels as well.
