PATCH: allow PE executables to have an export table

[Charles Wilson]

Tested on cygwin, works as advertised.  Updated patch attached (to apply 
cleanly to current CVS, and hopefully address the formatting issues).

Also, I found that there is a symbol that appears in .exe's that 
auto-export picks up on, but shouldn't.  So, this patch adds 
'cygwin_crt0' to the list of exclusions.

	* ld/pe-dll.c (process_def_file): don't create an export
	section if there are no exports and we're building an exe
	(pe_dll_build_sections): ditto
	(pe_dll_fill_sections): since this now gets called
	even when we're building an exe, conditionalize setting
	abfd->dll true on info->shared
	* ld/emultempl/pe.em (gld_${EMULATION_NAME}_after_open):
	if i386pe or armpe, call pe_dll_build_section()
	for both exe's and dll's, not just dll's.
	(gld_${EMULATION_NAME}_finish): for all targets except
	shpe and mipspe, call pe_dll_fill_sections() for both
	exe's and dll's, not just dll's.
