The warning was:
```
/home/rgommers/code/pixi-dev-scipystack/openblas/OpenBLAS/driver/others/memory.c: At top level:

 2565 | static void *alloc_hugetlb(void *address){
      |              ^~~~~~~~~~~~~
```

The added define is the same as is already present in the TLS part of
`memory.c`. This follows up on gh-4681.

The warning was:

The use of `volatile` for `newmemstruct` seems on purpose, and there are
more such constructs in this file. The warning appeared after gh-4451
and is correct. The `free` prototype doesn't expect a volatile pointer,
hence this change adds a cast to silence the warning.
