Fix for Typo + Theano Warning

[vvmurthy]

Two changes:

1. The argument to .theanorc is ldflags so that was changed as a result.

2. Theano throws a warning:

WARNING (theano.tensor.blas): We did not found a dynamic library into the library_dir of the library we use for blas. If you use ATLAS, make sure to compile it with dynamics library.

This fixes the warning.

I also found this typo. FYI, changing \n[blas]\nldflag = -L/usr/lib/openblas-base -lopenblas \ to \n[blas]\nldflags = -L/usr/lib/openblas-base -lblas \ also makes the warning disappear.
