[Xen-devel] [PATCH 7 of 7 v4] blktap3/tapback: Introduce tapback daemon Makefile

[Thanos Makatos <thanos.makatos@xxxxxxxxxx>]

This patch introduces the Makefile that builds the tapback daemon.

Signed-off-by: Thanos Makatos <thanos.makatos@xxxxxxxxxx>

---
Changed since v2:
  * Use $(BINDIR) as the daemon's installation directory.
  * Fixed whitespace.

Changed since v3:
  * Explicitly use libblktapctl.3 to avoid conflicts with the blktap2 one.
  * Merge patch that adds the tapback binary to the mercurial ignore list into
    this patch.
