update nginx compile switch -fstack-protector to -fstack-protector-strong if system supported in 123.09beta01

Enable strong stack protection for nginx source compiles when detected system supports it. "Strong" stack protection for GCC [LWN.net]

Works fine on tested CentOS 7's GCC 4.8.5 version but doesn't seem to compile properly with Clang 3.4.2.

So updated inc/nginx_configure.inc routine in Centmin Mod 123.09beta01 to detect if clang is used or when GCC version <4.8.5 is used it will use -fstack-protector. If GCC >4.8.5 detected i.e. CentOS 7, then nginx compile will use -fstack-protector-strong. Centmin Mod Nginx defaults to Clang 3.4.2 compiler out of the box unless ngx_pagespeed 1.10+ and higher are used (NGINX_PAGESPEED='y') or when Openresty Nginx Lua modules are enabled (ORESTY_LUANGINX='y') as they both require higher system GCC versions than what Clang can support to properly compile Nginx with those modules.

Centmin Mod centmin.sh menu option 4 for Nginx upgrade, downgrade or recompiles will automatically detect what your system supports GCC version wise and auto detects which nginx modules are configured and auto switch between GCC and Clang appropriately.

FYI, you can also force GCC usage instead of Clang using persistent config file /etc/centminmod/custom_config.inc and set

Code (Text):

CLANG='n'

and then run centmin.sh menu option 4 to recompile nginx with GCC. -fstack-protector-strong will then be used if centmin mod detects GCC >4.8.5
