This confers an >10x speedup on t/z-t/cmd builds (12s -> 1.1s), gets rid of 23 redundant identical automake specs and gitignores, and groups the binaries with their common headers Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Reviewed-by: John Kennedy <john.kennedy@delphix.com> Reviewed-by: Ryan Moeller <ryan@iXsystems.com> Signed-off-by: Ahelenia Ziemiańska <nabijaczleweli@nabijaczleweli.xyz> Closes #13259
