 What I did the last time I was laying out OS makefiles:
 
  - the recursive rule for a full build is "build" (not "all", which
 retains its traditional meaning);
 
  - there's a separate set of "stage-install" rules that hardlink or copy
 into $DESTDIR; the "install" target goes straight to the ultimate
 destination tree;
 
  - build is defined like this by default:
 
     # dependall means depend then compile, but it's important to run a
     # new make after depending so the new depends take effect.
     dependall-local: depend-local
 	    $(MAKE) all-local
     dependall: dependall-local
 
     # build means depend, compile, and stage-install; it also needs a
     # new make after depending. It could use the same one for compile
     # and stage-install, but that turns out to be awkward.
     build-local: dependall-local
 	    $(MAKE) stage-install-local
     build: build-local
 
 (-local means 'not in subdirs')
 
 
 This is probably not as parallelizable as one might wish, but it does
 AFAICT have the redeeming feature that it works, which the netbsd
 scheme doesn't quite always.
