Recreate the OS390-Unix config target

 Changes between 1.1.1 and 1.1.2 [xx XXX xxxx]

  *) Recreate the OS390-Unix config target.  It no longer relies on a

     special script like it did for OpenSSL pre-1.1.0.

     [Richard Levitte]

  *) Instead of having the source directories listed in Configure, add

     a 'build.info' keyword SUBDIRS to indicate what sub-directories to

     look into.
