-g only means that symbolic debug information is in the RTEMS libraries.
That symbolic information is included with your linked application 
unless strip it.

I would hazard a guess that there is no "standard" way. SOme people may
want to debug in the field.  Sometimes you have to convert to a specific
format to download.  But for sure if you are trying to shrink the file
size, get rid of the debug information.  See
