genoffset used the fully generic ASSYM macro to generate the offsets
needed for the thread_lite structure. However, since these are offsets
into a structure, they will always be necessarily small and positive. As
such, just create a simple character array of the right size and use a
naming convention such that we can recover the field name, structure
name and type. Use nm -t d and sort -n to sort these into order, then
loop over the resutls to generate the thread_lite structure.
