[Wien] Bug in seclr4.F (probably dsyxev4.f or dstebz2.f) for MKL_NUM_THREADS>1

[Laurence Marks]

Thinking about it, I suspect that with multiple-threads (which is
going to be with us for the new quad-cores) workspace requirements
will be larger by a multiple of the number of threads and this will
cause problems. While this maybe the first definitive case, I would
not be surprised if similar issues arise in other parts of the code. I
don't think the is a bug in mkl10.x, rather that there will need to be
some changes in the code due to how threads are handled.
