To my knowledge neither of these tools has a nice way to extract one
particular variable from .rodata. "readelf -p .rodata" comes close, but
not quite since we probably need the debugging symbols to find the right
variable in that list... An alternative would be to stick each
introspection blob into its own ELF section. But even then we'd still
need some ugly postprocessing of the readelf output?
