Description:
        When disabling the debugger support, the compilation fails
complaining about undefined shell_function_defs.

Repeat-By:
        Use --disable-debugger configuration option.

Fix:
        I started adding #if defined (DEBUGGER) to surround the code
that used shell_function_defs, but it seems there are still problems
to execute_cmd.c
