[PATCH] For posix compliance: replace index with strchr

[Cheng Renquan]

When compiled with other posix conforming libc, like uclibc,
it will fail with the lack of "index" function, in fact, index
is really legacy, and dropped in POSIX.1-2008

>From index(3):

  CONFORMING TO
       4.3BSD; marked as LEGACY in POSIX.1-2001.  POSIX.1-2008
       removes the specifications of index() and rindex().
