[PATCH v2 0/3] update sha1dc from PR #36

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

A v2 addressing comments to the v1, tbdiff below. Just fixes the
subject line on 1/3 & gets rid of the redundant _BIG_ENDIAN detection
for Solaris, we can just use __sparc (and indeed we did before this).

Junio C Hamano (1):
  sha1collisiondetection: automatically enable when submodule is
    populated

Ævar Arnfjörð Bjarmason (2):
  sha1dc: correct endian detection for Solaris (and others?)
  sha1dc: optionally use sha1collisiondetection as a submodule
