creating binaries by objcopy

First of all, just to be sure that there is no confusion here: when the 
binutils manual talks about a "raw binary" file it is talking about a 
file in one particular specific format.  It is not talking about any 
arbitrary binary file such as an ELF executable file, or an IHEX binary 
file.  It is talking about a *raw* binary file where essentially the 
only structuring is that the file could be loaded/mapped into memory and 
then executed by jumping to an address which the host OS must have found 
out through some other means.

Yes - do not use the raw binary format.  Stick with the ELF format.  Or 
if you must, choose a simpler format like IHEX or SREC.
