Subject: [PATCH] Add support for loongarch64 architecture in ld.hugetlbfs
- Added alignment configuration for loongarch64 architecture in the `ld.hugetlbfs` script.
- Set `HPAGE_SIZE` to 32MB and `SLICE_SIZE` to match `HPAGE_SIZE` for loongarch64.
- This ensures correct alignment and hugepage usage for binaries targeting loongarch64 systems.
Fix: https://github.com/libhugetlbfs/libhugetlbfs/issues/91
