OpenBLAS 64 bits on ARM

[matbesancon]

This follows #39436

I tried building it on an ARM machine. Make errors, presumably when compiling SparseSuite:

It's because SuiteSparse is linked against 32-bit openblas currently in BB on aarch64. Fairly easy fix.

[ViralBShah]

The issue here is suitesparse, where BB is picking the 32-bit build still for SuiteSparse 5.4.1. I think it is best I roll this into #39455, where I am moving to SuiteSparse 5.8. There SuiteSparse links to LBT, but it is already being built for 64-bit BLAS on aarch64.
