This is probably a problem with the pc386 BSP.  You may have a look at the 
linker map.  On ARM I have this:

arm-rtemseabi4.11-size o-optimize/app.exe
    text    data     bss     dec     hex filename
   26776    1752 33591424        33619952        200fff0 o-optimize/app.exe

This is a bit huge, since the POSIX API is enabled (which pulls in exit() etc.).
