opencv: backport commit to compile with ppc

During the testing of the meta-ros layer, I discovered that opencv
does not cross-compile for the ppc architecture. The error is
reported in the meta-ros issue tracker #355 [1]. To address this
error,  this commit applies a patch that is already provided upstream
in the opencv version 3.0.
