for that purpose, introduce QMAKE_RPATHLINKDIR_POST, and migrate all

QMAKE_RPATHDIR_POST is added for consistency, but not actually used.

The qt_poll function calls recv to query whether fds marked by select
as readable should be marked POLLIN or POLLHUP in the pollfd structure.
On many platforms such as QNX this requires extra link-time libraries
which were not previously required by QtCore.
While the qt_poll function is intended as a fallback mechanism only for
those platforms which do not implement poll natively, the function was
compiled unconditionally whenever QT_BUILD_INTERNAL was defined, e.g.
in developer builds.
Additionally the function was included on those systems that define poll
in system headers so that configure determines build-time availability,
but do not define _POSIX_POLL > 0 or indicate POSIX:2008 compliance via
either the _POSIX_VERSION or _XOPEN_VERSION macros. On those systems a
sysconf query for _SC_POLL was performed to determine at runtime whether
to call the system poll or qt_poll.
Both of these cases are in fact counterproductive. In the first case the
sole consumer of the function is a single manual unit test. In the
second, to my knowledge no platform requires the runtime fallback.
Despite that, we were forcing an extra dylib in both cases.
Both cases are fixed by 1) moving the implementation into its own file
for the unit test to include and 2) dropping the dynamic fallback if
configure determines availability of poll at compile-time.
This also reverts commit 1377709711, which
added -lsocket for QtCore on QNX.

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

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.

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.
