Log:
  Switch reproducible builds to unmodified src tree mode
  
  newvers.sh supports two modes for reproducible builds:
  
   -r    Reproducible build.  Do not embed directory names, user
         names, time stamps or other dynamic information into
         the output file.  This is intended to allow two builds
         done at different times and even by different people on
         different hosts to produce identical output.
  
   -R    Reproducible build if the tree represents an unmodified
         checkout from a version control system.  Metadata is
         included if the tree is modified.
  
  Switch to the second mode when reproducible builds are enabled.
  The value of a reproducible build is much less when building from an
  uncontrolled, modified src tree, and -R likely provides the best
  compromise in allowing the REPRODUCIBLE_BUILD knob to be enabled by
  default for the release.
