how to add debugger option to the build script

[Chan Kim]

Hi,
Is there any option for build-rtems.sh by which I can add '-g'(debugger) to CFLAGS in the result Makefile?
(I run '../build-rtems.sh' under build-rtems directory. The --enable_rtems_debug is for enabling RTEMS_DEBUG macro in the sources.
I want -g option to be added for gcc so that I can use debugger.)
Any suggestion will be appreciated.
