Cleaned up Build Variables sections
Everyone was referencing the x86 Build Variables section but now x86
has some unique variables. So created a common/vairables.xml from
the existing x86/variables.xml but removed parts that weren't common.
Now arm and mips both reference the common/variables.xml file and have
their unique parts.
