[Jprogramming] 64 bit lapack

[Scott Locklin]

I'm in the process of modifying the lapack addon for 64 bit linux. I had a very hard time building working shared libraries with the old CLAPACK source (last major update ... 1994 or so), so this is oriented towards the modern LAPACKE C interface. LAPACKE is part of the main Lapack distribution, and so it should be available everywhere, though I have no Mac or Windows machines to test there. 

The most important piece, geev, is working. gesvd kinda sorta works. Fixing the rest should be rote plumbing; I'll get to it in the next week or two.

I'm still pretty weak at writing J expressions, so if there are any comments, in particular in the lcall function in lapack.ijs, I'd appreciate it!
