Optimized build for the D-Link DIR-860L

@Bartvz Interesting post by @Borromini here: [Solved] WRT1900ACV1 reboots: kernel 4.9

Might be worth a try for these builds as well :slight_smile:

Edit: Disregard this post. This build already is compiled with GCC 6.3. Then maybe it is one of the commits? More testing is needed. Hopefully @Borromini can clarify whether cake was enabled.
