This linker script is only enabled for systems with GCC or GCC-like
compilers, though technically it should work on the BSDs too (will
enable after testing). For regular modules, this declares one ELF
version "Qt_5" and places all QtCore symbols inside, then it declares
unused ELF versions "Qt_5.x" for each older minor release. For modules
declared "internal_module", all symbols are placed in version
Qt_5_PRIVATE_API.
The big advantage of an ELF version is that, when we do Qt 6, both
versions of QtCore could be loaded in memory without conflicts and all
symbols would be resolved to the correct library. No module can talk to
both at the same time, but this avoids mistakes of loading them
indirectly by plugins.
The extra Qt_5.x versions will be used in the next commit.

[ChangeLog][General Improvements] Qt's buildsystem now detects whether
the compiler supports C++14 and experimental support for C++1z. If the
compiler supports it, then Qt is automatically compiled using that
support.
\
This does not apply to user applications built using qmake: those are
still built with C++11 support only. To enable support for C++14 in your
application, add to your .pro file: CONFIG += c++14 (similarly for
C++1z).

Replace all tabs with proper space characters and consistently align
the '=' characters. The default alignment for the '=' of 25 characters
has been left as is to get a minimal diff. Lines with the '=' further
to the right and those belonging to 'proper code (TM)' have not been
touched.
The work was mostly done using the following python script (might
come in handy again...):
import sys, re
indent_eq = 25 + 0*4 # 25 characters was the most widely used indentation for the '=' character
p = re.compile(r'(\w+)[ \t]*([\-\+]?)(=$|= )[ \t]*(.*$)')

nl = l
if m:

We do not need to include -lang-c++ more than once in QMAKE_LFLAGS*
variables. The fact that this was not appearing more than once was due
to QMAKE_LFLAGS being overwritten (rather than appended to) in
qcc-base-qnx.conf and a weird coincindence in qmake's code to dedupe
libraries passed in to QMAKE_LFLAGS. The deduping was working based
upon options beginning with "-l", including the -lang-c++ option here.

Making -lang-c++ integral part of the $CXX command was wrong, because there are
cases where $CXX must be called without the -lang-c++ file (when building asm
files for instance). This commit moves the -lang-c++ to $CXX_FLAGS where it
belongs.

Rationale:
QCC is a wrapper around GCC, but it doesn't understand -std,
so we need to pass it via -Wc.
The underlying GCC is v4.4, which doesn't know -std=c++11
yet, only c++0x.
We can't use -std=c++0x here, because the QNX headers
depend on some GNU extensions (nanosleep() was one that I
saw), so it has to be gnu++0x, ie. STD C++ + GNU extensions.
