[PATCH] sha1dc: update from upstream

["Ævar Arnfjörð Bjarmason" <avarab@gmail.com>]

Update sha1dc from the latest version by the upstream
maintainer[1]. See 07a20f569b ("Makefile: fix unaligned loads in
sha1dc with UBSan", 2019-03-12) for the last update.

This fixes an issue where HP-UX IA64 was wrongly detected as a
Little-endian instead of a Big-endian system, see [2] and [3].

Yeah that patch to git.git should be done separately. I see your PR
went in upstream, here's a patch to update our code to match.

Sure, makes sense. I'm not familiar with HP/UX. So just thought I'd
ask.
