sci-libs/scipy: disable parallel build completely.

  After 4 years discussion and debugging, we conclude that Python 3 is
  deeply broken in parallel builds for anything involving compiling of
  C/C++/fortran code.  The problem is universal, regardless how
  dev-python/numpy is built.

  Numpy and scipy upstream cannot do anything about this.  We bite the
  bullet and disable parallel build of scipy completely.

  Thanks to all who have contributed to this heroic marathon
  debugging.  We regret that only a workaround can be provided at this
  moment.
