Don't bootstrap QT_EVAL code

For most bootstrapped tools, the QT_EVAL code will not
have any effect, because most of the tools don't instantiate
a QCoreApplication. However, qdoc is bootstrapped for cross
compilation, and will instantiate QCoreApplication which
calls the QT_EVAL code. Since the QT_EVAL code requires QObject,
and QObject requires moc, it does not make sense to compile the
eval code into the bootstrap library. Instead, we simply disable
it to make sure the build succeeds.

Mark that GCC 4.8.1 has support for C++11 member reference qualifiers

This also marks it feature-complete for C++11 (at least, language
features). See http://gcc.gnu.org/gcc-4.8/cxx0x_status.html and
http://gcc.gnu.org/projects/cxx0x.html.

Support for the C++11 features in the Standard Library is still
incomplete, but we don't try to detect those features anyway (see
http://gcc.gnu.org/onlinedocs/libstdc++/manual/status.html#status.iso.2011).
