I have not looked in the sources until now.

If this information will be written to any non text or data section it
seems ok. To add any kind of meta data section like debug and config
sections to an elf file can not disturb any other feature, so I think it
is a good way.

But I personally want to overwrite the informations from the elf file by
config options on the command line. Maybe I want a different clock
frequency or maybe a smaller controller. This MUST be possible without
rebuilding the elf file.

Simply the information can be read out from elf and if any options are
on the command line they overwrite the infos from file.

If so: Do it :-)
