[ECOS] ARM EP7xxx ROM image - gcc -g omission requirement

[AshCan@aol.com]

Cirrus Logic has an application note for building ecos
based systems for the EP72xx family of processors.  

Page 12 of the app note lists requirements for building
a ROM image for download.  

One of the items states "build your application without
the debugger option -g."

I did build with and without -g and diff'd the two 
binary files generated by arm-elf-objcopy.  
Sure enough they are different even though the byte 
count is the same.

Can someone explain why this requirement exists, why 
the .bin files are different, and what effect the 
difference has?
