As nobody answers....

AFAIK, there is still no comfortable way to switch between debug/optimized 
versions of RTEMS.

This is the way I did this for 4.8.0:

1. I have two symbolic links to two different build trees - one for debug and 
one for optimized.

To create for the first(!) time the desired version I went to  the 
rtems-source/make/custom/mybsp.cfg file and corrected the line:
CFLAGS_OPTIMIZE_V=... -O0....

Then I did everything from the beginning: bootstrap, config.....

The resulting build tree I called rtems-dbg.


2. Repeted all above with CFLAGS_OPTIMIZE_V=... -O4....
The resulting build tree I called rtems-opt.

Finally, I made a symbolic link which I called "rtems" which is used in all my 
application make files in the IDE.

Now, I switch the link to dbg or opt when desired.

That is. Obviously, not the best way, but it works.
