 * Global include file for linker debugging.
 *
 * ld(1) and ld.so carry out all diagnostic debugging calls via dlopen'ing
 * the library liblddbg.so.  Thus debugging is always enabled.  The utility
 * elfdump() is explicitly dependent upon this library.  There are two
 * categories of routines defined in this library:
 *
 *  o	Debugging routines that have specific linker knowledge, and test the
 *	class of debugging allowable before proceeding, start with the `Dbg_'
 *	prefix.
 *
 *  o	Lower level routines that provide generic ELF structure interpretation
 *	start with the `Elf_' prefix.  These latter routines are the only
 *	routines used by the elfdump() utility.
