How to make a debug build for hello?

Hi everyone!

I'm new to RTEMS, and having this question.

For short, how could I build application with DEBUG enabled?

What I have done:

1. Building RTEMS kernel with stm32f4 bsp with following options:
../rtems/configure --prefix=`pwd`/../../4.11.3 --target=arm-rtems4.11
--disable-networking --enable-rtemsbsp=stm32f4 --enable-tests

2. Preparing my own hello application:
    mkdir myhello; cd myhello
    cp $RTEMS_KERNEL_ROOT/rtems/testsuites/samples/hello/init.c  hello.c
    cp $RTEMS_BUILD_ROOT/share/rtems4.11/make/Templates/Makefile.leaf
    edit Makefile according to its README under Templates
3. Building myhello

> test -d o-optimize || mkdir o-optimize
> arm-rtems4.11-gcc --pipe
> -B/home/xxxx/yyyyy/RTEMS/kernel/stm32f4/../../4.11.3/arm-rtems4.11/stm32f4/lib/
> -specs bsp_specs -qrtems   -Wall  -O2 -g     -march=armv7-m -mthumb
>  -c   -o o-optimize/hello.o hello.c
> arm-rtems4.11-gcc --pipe
> -B/home/xxxx/yyyyyy/RTEMS/kernel/stm32f4/../../4.11.3/arm-rtems4.11/stm32f4/lib/
> -specs bsp_specs -qrtems   -Wall  -O2 -g     -march=armv7-m -mthumb
>   -march=armv7-m -mthumb   -o o-optimize/hello.exe  o-optimize/hello.o
> arm-rtems4.11-nm -g -n o-optimize/hello.exe > o-optimize/hello.num
> arm-rtems4.11-size o-optimize/hello.exe
>    text    data     bss     dec     hex filename
>   69572    1660  129416  200648   30fc8 o-optimize/hello.exe
> cp o-optimize/hello.exe o-optimize/hello.ralf

however if I build with debug it failed:

> make clean; make debug
> make -f Makefile MAKEFILE=Makefile VARIANT=DEBUG
> make[1]: Entering directory '/home/xxxx/yyyyyy/RTEMS/prjs/myhello'
> test -d o-debug || mkdir o-debug

>  -c   -o o-debug/hello.o hello.c

 I try to rebuild BSP with --enable-rtems-debug flag, it also didn't
generate *_g.a files.

So how could I build BSP with debug enabled?
