[OpenJDK 2D-Dev] [PATCH FOR REVIEW] Building ExtensionSubtables.cpp should use -fno-strict-aliasing

I have one concern

It sounds like the option is new in gcc 4.4 : 

I am not sure you can assume that since ..

" The GNU gcc compiler version should be 4.3 or newer."

And I suggest a push to 2d-dev since its in the 2d code we get
a warning and the "build" change is in 2D build files, specifically to work
around that warning .. its really precious little to do with the build
