Octave 4.0 rc2 on Ubuntu 14.04 on Amazon EC2

[SunilShah]

 I did a build of  Octave 4.0 rc2 on Ubuntu 14.04 (LTS) on EC2 on a
c4.8xlarge instance.  

The configure settings used openblas-base and lapack to allow use of
available cpu cores for large matrix operations.

Here is the result of make check 

Summary:

  PASS     12827
  FAIL        13
  XFAIL       15
  SKIPPED     64

The fails are in 

libinterp/corefcn/graphics.cc-tst ........................... PASS     34/37  
                                                                  FAIL    3

scripts/gui/uimenu.m ........................................ PASS      0/3   
                                                                  FAIL    3

scripts/plot/util/allchild.m ................................ PASS      2/3   
                                                                  FAIL    1
scripts/plot/util/findall.m ................................. PASS      0/1   
                                                                  FAIL    1
scripts/sparse/eigs.m ....................................... PASS   
152/154 
                                                                  FAIL    2
scripts/sparse/svds.m ....................................... PASS      5/6   
                                                                  FAIL    1

I was wondering if these are expected.   

I did test that dense matrix operations like lu use all available cores on
sufficiently large matrices.
