Description:
------------
In php_cli_server, we use a static const struct timeval

According to select man page :
   "(ii)   select() may update the timeout argument to indicate how much time was left."

Removing the "static const" solves this issue.

Test script:
---------------
$ gdb sapi/cli/php
(gdb)  run -S 127.0.0.1:8000


Expected result:
----------------
PHP 5.5.13 Development Server started at Tue Jun 10 03:08:42 2014
Listening on http://127.0.0.1:8000
Document root is /discer.farm/home/remote/rcollet/rpmbuild/BUILD/php-5.5.13
Press Ctrl-C to quit.



Actual result:
--------------
Program received signal SIGSEGV, Segmentation fault.
