Bug description:
  SRU Justification:
  ==================

  [ Impact ]

   * The dbginfo.sh script fails on system (actually shells) that run dash,
     due to some incompatibilities in dbginfo.sh (with using 'type').

   * The script fails with a with parameter error.

  [ Fixes ]

   * 92b84092 92b84092077f5238f8067f24e9fc330ddefb4525 "dbginfo.sh:
  ensure type commands compatible with dash"

   * 9f93af61 9f93af614f7463317ec56af5a6484f66386af797 "dbginfo.sh:
  ensure compatibility with /bin/dash"

  [ Test Plan ]

   * Use a user account that has dash as default shell,
     or simply call dash in whatever shell you are running.

   * Make sure the s390-tools are installed (but it's mandatory for s390x)
     since dbginfo.sh is included into this.

   * Now call /usr/sbin/dbginfo.sh (from within a dash shell)
     and watch out for any errors,
     esp. some caused by issues with parameters,
     like 'type' is not supporting '-t'.

  [ Where problems could occur ]

   * The changes in handling the parameters could break the dbginfo.sh
     on other shells, like bash (which is the default in Ubuntu).

   * Fortunately the changes in the above commits are pretty traceable.
