Is there a way to strip out the debugging information from an image
compiled with -g? I would like to have an image without debugging info,
especially for the bootblock and initram because both are uncompressed
and storing uncompressed debug info in a ROM is a total waste of space.
The debugging info for each LAR member can be stored in a separate
(always compressed) member.

By the way, the debugging info is similar to one of the pet projects I
have: Providing a symbol file for the boot block, enabling people to
build initram and stage2 against a given bootblock.

Patch available if anybody is interested.
