1. Do not install FILES/SCRIPTS multiple times if PROGS is specified; this is already handled via bsd.prog.mk when it's called recursively (PR: 191055, 191955). 2. Some variables, like BINDIR and PROGNAME, default to a value if unset whereas others get appended to, like CFLAGS. Add support for the former case (PR: 191056) 3. Make "checkdpadd" and "clean" available targets for recursive execution. Reviewed by: marcel, sjg Phabric: D822 PR: 191055, 191056, 191955 MFC after: 1 week Sponsored by: EMC / Isilon Storage Division
