Provide a way to compile some files with -O0 option
When preparing an image for source level debugging, it is convenient
to be able to compile some modules with -O0, which makes it much
easier to follow the execution flow.
This patch allows to do it by defining GDB_DEBUG=1 in the environment
before invoking make. Adding this feature as a common config flag is
problematic, because we don't want to compile the entire image with
-O0.
