gcc: backport patch affecting Linux kernel builds

A long-standing bug in gcc turns out to cause problems with unpatched
Linux versions due to improved optimization enabled by gcc 4.9.  The
upstream fix missed the gcc-4.9.1 cut-off.  It's also been applied
upstream to the 4.8 branch so is being added for OE's 4.8 as well.
