In looking at the JS Value encoding in src/qml/common/qv4staticvalue_p.h, I suspect there might be
an issue with NaN/Inf values on hppa. hppa and early mips used a different representation for signalling
and quiet NaNs. This would need to be taken into account in converting between JS and hardware values.
It seems hppa is the only big endian ilp32 architecture.
