determine compiler version at build time, not in configure this makes it consistent with the determination of the default include/library paths. this makes sense, as it's possible to switch the sdk/toolchain after building qt (within reason). a side effect of this change is that for compilers which emulate other compilers, both the real and the emulated version are now made available.

Detect the (stated) C++ standard edition at build time The configure-time detection (cxx11default) isn't enough if the compiler can be changed. This is especially necessary if Qt is compiled with a compiler that defaults to >= C++11 (e.g., GCC 6) and then the user selects a compiler another compiler (e.g., Clang) via -spec option. In that case, we'd miss adding the -std=c++11 or -std=gnu++11 option to the command-line, causing the compilation to fail. As a nice side-effect, even moc without moc_predefs.h will now get the __cplusplus setting.
