There was a small window between <stdlib.h> referencing it and
__unsetenv13() actually being built into libc, but this shouldn't be
biting you if your sources are really -current.

I've added __unsetenv13 to UPDATING since it already happens to
mention __assert13, but except for said small window of failure it's
really nothing that wouldn't be taken care of by an in-order performed
build of the system.
