Robert Clausecker b2618b651b lib/libc/amd64/string/memchr.S: fix behaviour with overly long buffers 
When memchr(buf, c, len) is called with a phony len (say, SIZE_MAX),
buf + len overflows and we have buf + len < buf.  This confuses the
implementation and makes it return incorrect results.  Neverthless we
must support this case as memchr() is guaranteed to work even with
phony buffer lengths, as long as a match is found before the buffer
actually ends.
