1.6.2 JNA conflict

[rodrigopitanga]

Arduino 1.6.2 will crash after splash screen. Looks like it requires a non-standard library.

see also #2830 and #2829, think its a missing hardware directory not a java library issue?

Looks like the function com.sun.jna.Native.pointerSize(Native Method) is not available. I could not find any reference to pointerSize in https://github.com/twall/jna. Unfortunately, I don't know enough Java to identify the issue further. But, yes, the hardware directory is empty.

Fixed with b65b576. A nightly build is on the way
