Subject: [PATCH] snappy: Autospec creation for version 1.1.9

This patch addresses an issue with Ceph
https://tracker.ceph.com/issues/53060. There have been multiple patches
to upstream snappy, but they have all been rejected and the reasoning
has always been that snappy would like to be consistent in their build
flags with chrome as mentioned at
https://github.com/google/snappy/pull/144#issuecomment-968371042
