I actually doubt it's Linux-specific (more like all Unix), but the
changes are in files called "linuxaccessibility".

We should carry this in all 5.5.x and 5.6.x releases, to make sure
everyone gets the message. But for this release, we need to note the
changes from what was announced for 5.5.0:
Clang 3.2 cannot compile std::atomic properly, so it will not be
supported. That means the minimum XCode version we'll require will be
5.1, which fortunately does not raise the minimum OS X version that can
compile Qt. See http://llvm.org/bugs/show_bug.cgi?id=12670 for more
information.
ICC 14.x and 15.x on Windows miscompiles pointer-to-members across DLL
boundaries, so signal-slot connections fail. See QTBUG-40281.

The -fPIE option is now accepted when using GCC 4, which means it
is available for backward compatibility for clients using
CMake 2.8.11 or older which makes use of the
POSITION_INDEPENDENT_CODE feature.
Conditionally use that feature for old versions of cmake with
GCC 4. Restore the tests for those versions, and clarify the
situation in the ChangeLog.

Prior to Qt 5.4.2 (commit 36d6eb721e), we
allowed it, but now we need to enforce that it is not used. Note that
-fPIE does define __PIC__, so we need this to catch the use of -fPIE.
[ChangeLog][Important Behavior Changes] On x86 and x86-64 systems with
ELF binaries (especially Linux), due to a new optimization in GCC 5.x in
combination with a recent version of GNU binutils, compiling Qt
applications with -fPIE is no longer enough. Applications now need to be
compiled with the -fPIC option if Qt's option "reduce relocations" is
active. Note that Clang is known to generate incompatible code even with
-fPIC if the -flto option is active.

The default should be the actual time of day. Showing the process's time
is the optional case. In the future, we'll provide a way to showing the
monotonic reference time ("boot") and we should improve the detection of
actual application runtime.
