Merge branch 'ti/external-sha1dc'
Platforms that ship with a separate sha1 with collision detection
library can link to it instead of using the copy we ship as part of
our source tree.
* ti/external-sha1dc:
sha1dc: allow building with the external sha1dc library
sha1dc: build git plumbing code more explicitly
