Update to 0.38beta1

  In order to minimize total build time, heavier packages are built
  first.  This is implemented with a help of recent paexec(1).  Simple
  heuristics using source size is used to guess build time of the
  package.  Probably this heuristics needs to be improved.
  Recent paexec >= 0.15.0 is required

  distbb now conforms to POSIX Utility Syntax Guideline.
  Recent runawk >= 1.1.0 is required.
