Below is a revised patch incorporating recent feedback. Changes:
* remove blank lines at EOF
* add gcc/cobol/lang.opt.urls
* simpllify gcc/cobol/config-lang.in (and FE requires C++)
* add stub gcc/cobol/ChangeLog
* group ChangeLog entries by directory
* support --enable-generated-files-in-srcdir
* remove reference to --fdump-generic-nodes option

done.
The patch previous reported "9 files" but contained only 8. We added
2, so the total is now 10.
As before, this patch comprises all the "meta files" needed for the
Cobol front end, including every existing file that we modified.
1. It does not interfere with --languages=c,c++, etc
2. It does not work with --languages=cobol because the source files
are missing.
I have not tested with git-gcc-verify because I don't know how to use
it It does apply cleanly with "git am" (on my end, at least).
