commit cb8263770e4f5834a43db6be8ffb55ffd7f876c9
Changed rteval to allow running on low memory systems by default because
on some machines, such as certain Arm boards, it isn't a problem.
However, on our automated testing systems it is causing problems.
This patch disables running hackbench by default on a low memory system.
In order to allow people to run on a lowmem system where this isn't a
problem, this patch also creates the option
--hackbench-runlowmem=True|False
A user who wants hackbench to run in rteval on a low memory system, only
needs to specify
--hackbench-runlowmem=True
