bde c900f7bd6f Removed bogus env(1) commands. make(1) uses a real shell, so
"env name=value ... cmd ..." was just a pessimized way of doing
"name=value ... cmd ...".  Note that make(1) can't optimize
either of these to an exec of env(1) or "cmd" even if the second
"..." is simple, since it can't tell that the shell metacharacter
in "name=value" is actually handled by env(1).
