    Makefile: fix unaligned loads in sha1dc with UBSan · 07a20f56
    Jeff King authored
    The sha1dc library uses unaligned loads on platforms that support them.
    This is normally what you'd want for performance, but it does cause
    UBSan to complain when we compile with SANITIZE=undefined. Just like we
    set -DNO_UNALIGNED_LOADS for our own code in that case, we should set
    -DSHA1DC_FORCE_ALIGNED_ACCESS.
    
    Of course that does nothing without pulling in the patches from sha1dc
    to respect that define. So let's do that, too, updating both the
    submodule link and our in-tree copy (from the same commit).
