description:
Register new weak symbol in libc for internal usage: asctime

The NetBSD Standard C Library uses internally some of its functions with
a mangled symbol name, usually "_symbol". The internal functions shall not
use the global (public) symbols.

Add asctime to namespace.h.

Register a new __weak_alias() entry for asctime() in asctime.c.

acstime() is used internally in ctime and __ctime50. This revision switches
the internal usage to the internal symbol.
