PATCH 1/1 ARM: optimize for FA526 if toolchain supports it

Currently, when we are targetting a Farady FA526-based system the toolchain will use the arm9tdmi mtune option of gcc, gcc > 4.6 supports the FA526 CPU, and allow us to optimize for it.

No objections to the patch, but a question out of curiosity:

Is this the regular gemini platform that you are working on, or something else? Do you have other platform support patches that you are planning to submit for this?

I need this on a different platform (Moschip MCS814x), which I will be submitting once I have all the bits working and converted to device tree. --

Ok, good to know.
