DJ Delorie eb8061bf35 * pe-dll.c: New file; direct support for PE DLLs
* deffile.h: New file; direct support for PE DLLs
	* deffilep.y: New file; direct support for PE DLLs
	* emultempl/pe.em: add direct support for PE DLLs
	* configure.tgt: allow target-specific extra files
	* configure.in: allow target-specific extra files
	* ldlang.c (lang_add_assignment): return the assignment so that
 	one can change the value later based on the object files (pe-dll
 	DEF files do this)
	* ldint.texinfo: add section for emulation walkthrough

This file turns a regular Windows PE image into a DLL. Because of
the complexity of this operation, it has been broken down into a
number of separate modules which are all called by the main function
at the end of this file. This function is not re-entrant and is
normally only called once, so static variables are used to reduce
the number of parameters and return values required.
