 * @brief RTEMS Module Loading Debugger Interface.
 *
 * Inspection of run-time linkers in NetBSD and Android show a common type of
 * structure that is used to interface to GDB. The NetBSD definition of this
 * interface is being used and is defined in <link.h>. It defines a protocol
 * that is used by GDB to inspect the state of dynamic libraries. I have not
 * checked GDB code at when writing this comment but I suspect GDB sets a break
 * point on the r_brk field of _rtld_debug and it has code that detects this
 * break point being hit. When this happens it reads the state and performs the
 * operation based on the r_state field.
