This makes packages use lapack and blas, which can wrap different
BLAS/LAPACK implementations.
treewide: cleanup from blas/lapack changes
A few issues in the original treewide:
- can’t assume blas64 is a bool
- unused commented code
- mxnet now builds the open source MKL DNN library. However, this
was not included with the build.
- mxnet builds its own OpenMP library, even when OpenMP is provided
by the system. This leads to problems, so remove the included
OpenMP implementation:
