Bring in a number of changes from NetBSD's make, fixing quite a few

problems in the process:

1. Quoting should work properly now.  In particular, Chet's reported bash
   make problem has gone away.
2. A lot of memory that just wasn't being free'd after use is now freed.
   This should cause make to take up a LOT less memory when dealing with
   archive targets.
3. Give proper credit to Adam de Boor in a number of files.
Obtained from: NetBSD (and Adam de Boor)
