I've just tried building head-of-git on my SheevaPlug to see what the
benchmarks are like; the SheevaPlug is interesting because its processor
is a different genus from most other ARMs out there, being descended
from the old StrongARM architecture.

Unfortunately after building it just fails:

$ luajit-2.0.0-beta6
LuaJIT 2.0.0-beta6 -- Copyright (C) 2005-2011 Mike Pall. http://luajit.org/
luajit-2.0.0-beta6: attempt to call a nil value

Is there anything special I need to do to build the ARM version? It
*looks* like it's autodetected the ARM (build log messages about x64
notwithstanding).
