* acinclude.m4 (GLIBCC_ENABLE_SYMVERS):  Tweak comments.  Add
	warning messages if the environment cannot support symbol versioning.
	(port_specific_symbol_file):  It's plural, add an 's' on the end.
	* configure.host:  Likewise.
	* src/Makefile.am:  Likewise.
	* config/linker-map.gnu:  Remove one semicolon, heh.
	* scripts/extract_symvers:  Don't assume useful 'export' syntax.
	Set LANG as well as LC_ALL for possibly-broken sort(1)s.
	* aclocal.m4, configure, src/Makefile.in:  Regenerated.
