Benchmark for Raspberry Pi 2

This test excluded the spawn test by removing the spawn item in pgms/index.base. The spawn test would otherwise randomly hang as the parent process waits for a futex resulting in the child process turning into a zombie.

Results Overview

Hardware	Raspberry Pi 2 Model B v1.1
CPU	BCM2836 @ 900MHz
Memory	1 GB
Disk	16 GB Kingston SD
Operating System	Arch Linux
Score	229.5 / 645.5 (without spawn test)
