I don't know but I can reproduce it with bmake on my Linux laptop.  It's
interesting, though, that as soon as you insert any bit that looks like
shell it stops execve-ing /some/path/from/PATH/cd:

        all:
                -cd /foo
                # cd /foo
                # bmake: exec(cd) failed (No such file or directory)
                # *** Error code 1 (ignored)

                -cd /foo /bar
                # cd /foo /bar
                # bmake: exec(cd) failed (No such file or directory)
                # *** Error code 1 (ignored)

                -cd /foo \#
                # cd /foo \#
                # /bin/sh: line 0: cd: /foo: No such file or directory
                # *** Error code 1 (ignored)

Note: First two errors are by bmake, the last one by /bin/sh.
