[patch ld]: Fix duplicates in export-table due missing set of is_ident.

[Kai Tietz]

Hi,

I missed here the import-case, so I resent.  This patch avoids
double-entries for first or last element search.  We missed
to set for identity is_indent in those cases.

ChangeLog

2012-02-13  Kai Tietz  <ktietz@redhat.com>

	* deffilep.y (find_export_in_list): Set is_indent for
	first or last element, if identical.
	(find_import_in_list): Likewise.
	
ested for i686-w64-mingw32, and x86_64-w64-mingw32.  Ok for apply?

Regards,
Kai
