MAKE MAGICBROWNIES!

PS2: It's impossible to make Lokesh happy :P
PS3: ERRRR
PS4:Fix everything

This commit is for Lokesh, I really want him to get his builds down to 18 mins. Here's rooting for ya lokesh!

To use: Run "make magicbrownies" and it will clear only the out/target/product folder, for hopefully, faster builds.
