Interestingly enough, such a thing has actually been implemented (look,
I know what "Loof Lirpa" backwards is, but what the heck?).

In Tektronix's UTek system, the strip command has options that allow
you to do things like run strip on a file and put the output in another
file (Andrew Klossner had an application where he was copying a huge
object file and then stripping it, and it was worthwhile to have strip
be able to do this in one shot to save time) and an option to put the
stripped string table into a separate file.

The resulting string table file contained the original header with a
special magic number (I think) so that it could be put back in the
object file.

Another command, called unstrip (what else?), could be used to put
the files back together.

The idea was that we could ship stripped binaries around and put the
header back on when we needed to debug it.

If you could do this with sdb or dbx information, you'd really have
something!
