configure.ac: Revise configuration report.

* configure.ac: Revise configuration report for intelligibility.  Add
  report of C++ compiler and flags used: we compile much more C++ than C
  code so this seems appropriate.  Report Perl interpreter version so
  that we can collect build reports and turn the ratchet past Perl 5.6.1
  at some point.  Fix X11 "resources" misnomer (application defaults are
  what is meant).  Rephrase generally.
