[Developers] newfmin on GPU with aribitrary number of variables

[dave fournier]

Just to point out that you do not need to link df1b2qnm.cpp so you can
remove it from mygccs

Another thought is that we should have a trivial test kernel or two
to make sure that the GPU stuff works.

Also check the amount of memory that is available on the GPU
for the main buffer to hold the matrix.

None of this is very difficult, but it would help a lot since we are all 
beginners
on this and it is difficult to diagnose problems.
