acinclude.m4 (GLIBCPP_CHECK_LINKER_FEATURES): Also check version.

2002-02-20  Phil Edwards  <pme@gcc.gnu.org>

	* acinclude.m4 (GLIBCPP_CHECK_LINKER_FEATURES):  Also check version.
	(GLIBCPP_ENABLE_SYMVERS):  Redo logic, use linker version.
	* configure.in (GLIBCPP_ENABLE_SYMVERS):  Move later in the script.
	* aclocal.m4:  Regenerate.
	* configure:  Regenerate.
	* config/linker-map.dummy:  New file.  Contains nothing useful.
