Make CONFIG += c++11 by default not disable GNU extensions
Prefer -std=gnu++11 unless strict_c++11 is defined. You can enable
strict C++11/C++14 mode by using
CONFIG += strict_c++
That is enabled for Qt's own code, so we we don't accidentally use GNU
extensions in portable code.
There's no support for strict C++98 mode (that is, the -ansi option).
[ChangeLog][qmake] By default, GNU extensions are now enabled with
Clang, GCC and ICC even in C++11 and C++14 modes. To disable the GNU
extensions, add to your .pro file: CONFIG += strict_c++.
