The presence or absense of debug info in the ELF file has no
impact on the footprint of the image.  I used to enable
debug symbols for kernel files when I was troubleshooting
eCos internal stuff, and it didn't require any more memory.

True, but his problem is that he wants debug info for the stuff
that is used.
