Just omitting "-reduce-relocations" doesn't change anything. For reference, http://paste.ubuntu.com/11431050/ lists the changes that I tried first - enabling the four commented out patches, modifying the enable_pie.patch accordingly which is actually also from upstream even though listed as being Ubuntu specific, and adding the gcc5.patch.
