Fix make_etags failure on Mac.
Previously make_etags always ran make_ctags -e when make_etags wasexecuted. However, because non-Exuberant ctags on Mac does notsupport -e option (and also on other platforms including old Linux),ctags failed. To avoid the failure change make_ctags so that ifnon-Exuberant ctags is used and ctags -e option is requested, runetags command instead. If etags command does not exist, make_ctagswill fail.Also refactor make_ctags and tweak make_etags to emit proper usagemessage.Author: Fujii MasaoReviewed-by: Tatsuo IshiiDiscussion:https://www.postgresql.org/message-id/369c13b9-8b0f-d6f9-58fc-61258ec8f713%40oss.nttdata.com
