OpenBLAS flag updates to address #1877 (#1914)

- Addresses #1877 
- #1746 introduced an issue in the pytorch workflows, which aren't
included in pre-submit CI, so the issue was missed then.
- Switching back to `C_LAPACK` for now as quickest solution.
- `CMAKE_CROSSCOMPILING` is not needed for our current use case.

# Test Plan
- Trigger the pytorch workflows to verify fortran issue is not present.
