Renamed all patches file names so that locales are now irrelevant to sort the files.

Removed the locale check as it is now irrelevant.
Removed the experimental binutils 2.17.50.0.xx: 2.18 is here now.

+Wildcard section matching enhancement, backported from the binutils CVS tree.
+Here's the CVS log comment from the original change to ldlang.c:
+
+revision 1.177
+date: 2005/04/06 15:33:02;  author: jakub;  state: Exp;  lines: +438 -51
+2005-04-06  Jakub Jelinek  <jakub@redhat.com>
+
+        * ldlang.c: Formatting.
+        (walk_wild_consider_section): Remember return value from wildcardp.
+        (is_simple_wild): Use strcspn instead of 2 strpbrk calls and strlen.
+        (wild_spec_can_overlap): Use strcspn instead of strpbrk and strlen.
+
+2005-04-06  Robert O'Callahan  <rocallahan@novell.com>
+
+        * ld.h (lean_section_userdata_type): Remove.
+        (fat_section_userdata_type): Remove file field.
+        (SECTION_USERDATA_SIZE): Remove.
+        * ldlang.c (init_os): Eliminate initialization of unused
+        lean_section_userdata_type.
+
+        * ldlang.h (callback_t, walk_wild_section_handler_t): New
+        typedefs.
+        (struct lang_wild_statement_struct): Add walk_wild_section_handler
+        and handler_data fields.
+        * ldlang.c (callback_t): Removed.
+        (walk_wild_consider_section, walk_wild_section_general,
+        section_iterator_callback, find_section, is_simple_wild,
+        match_simple_wild, walk_wild_section_specs1_wild0,

+        walk_wild_section_specs3_wild2, walk_wild_section_specs4_wild2,
+        wild_spec_can_overlap, analyze_walk_wild_section_handler): New

+        (lang_add_wild): Call analyze_walk_wild_section_handler.
+        (walk_wild_section): Renamed to walk_wild_section_general and
+        created a wrapper function.
+        (section_iterator_callback_data): New typedef.
+
+Note that bfd_get_section_by_name_if didn't exist in 2.15, so it was backported
+as well.
