Description:
------------
If the include configuration option is enabled, but the pool directory is empty, php-fpm crashes pretty ugly.

I could manage to enable the service by creating an empty default.conf file within the fpm.d directory, but obviously this isn't the solution. The used FPM is the latest trunk indicated by php-fpm.org http://svn.php.net/repository/php/php-src/trunk/sapi/fpm.

Test script:
---------------
The include line is:
include=/usr/local/zend/etc/fpm.d/*.conf

root@test-lucid:/usr/local/zend/etc/fpm.d# ls -la
total 8
drwxr-sr-x 2 root zend 4096 May 12 11:59 .
drwxrwsr-x 7 root zend 4096 May 12 11:59 ..
root@test-lucid:/usr/local/zend/etc/fpm.d#

Expected result:
----------------
To be able to start the php-fpm service just with the default pool from php-fpm.conf if fpm.d is empty. In my humble opinion the application shouldn't crash if no pattern is matched.

Actual result:
--------------
May 12 12:10:52.239695 [ERROR] Nothing match the include pattern '/usr/local/zend/etc/fpm.d/*.conf' from /usr/local/zend/etc/php-fpm.conf at line 10.

The backtrace is quite useless since the error is generated by sapi/fpm/fpm/fpm_conf.c, after the glob() call.
