Port to hosts whose 'sort' and 'tail' implementations treat operands with leading '+' as file names...
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.
