re PR libstdc++/22109 (/home/dave/opt/gnu/bin/ld: BFD 2.16.91 20050612 internal error)

	PR libstdc++/22109
	* src/compatibility.cc (_GLIBCXX_SYMVER_COMPATIBILITY): Remove.
	(istreambuf_iterator, basic_fstream, basic_ifstream, basic_ofstream,
	_M_copy, _M_move, _M_assign, _M_disjunct, _M_check_length,
	_M_set_length_and_sharable, ignore, eq): Define to XX suffixed
	variants.
	(ignore (streamsize)): Remove _W prefixed aliases.
	(_GLIBCXX_3_4_SYMVER_SPECIAL, _GLIBCXX_3_4_5_SYMVER_SPECIAL,
	_GLIBCXX_APPLY_SYMVER_SPECIAL): Remove.
	(_GLIBCXX_3_4_SYMVER, _GLIBCXX_3_4_5_SYMVER): Add XXname argument.
	Use #XXname instead of #name as the alias argument.
	* config/abi/compatibility.h: Replace uses of
	_GLIBCXX_APPLY_SYMVER_SPECIAL with _GLIBCXX_APPLY_SYMVER.  Always
	pass 2 arguments to the _GLIBCXX_APPLY_SYMVER macro.
	* include/bits/char_traits.h (char_traits::eq): Revert 2005-06-15
	change.
	* acinclude.m4: Decrease glibcxx_min_gnu_ld_version back to 21400.
	* configure: Rebuilt.
