You just have to change the compile flags somewhere.

You don't need to do that.  The debug symbols don't take up
target memory.

If you're running from RAM, all you have to do is connect via
the JTAG port and load the program using GDB.  GDB will "strip"
the image as it's being loaded into target memory.

IIRC, the trick was to get them there in the first place, but
I may be remembering incorrectly.
