New builder: SuperLU_MT (#983)

* Build SuperLU_MT

* With OpenMP instead

* Use double precision

* Address some build issues on not-Linux

* Use 64-bit integers when available

* Use 32-bit OpenBLAS

* Create a separate product for each precision

* Rename patch

* Never use long ints for indexing
