Port to hosts whose 'sort' and 'tail' implementations

	treat operands with leading '+' as file names, as POSIX
	has required since 2001.  However, make sure the code still
	works on pre-POSIX hosts.
	* libjava/classpath/ltmain.sh: Don't assume "sort +2" is
	equivalent to "sort -k 3", since POSIX 1003.1-2001 no longer
	requires this.
	This uses the same fix that is already in
	libjava/libltdl/ltmain.sh.
