I have to think about this one.
Should we try to handle unaligned access in the xlateto functions?
Those functions make use of a lot of tricky macros, which depend on the types
passed in.
Or should we fix the called (dwfl_segment_report_module) to only pass correctly
aligned buffers to the xlateto function?
The xlate functions translate between big/little endian on-disk/in-memory Elf
datastructure representations.
