eventfd(7) uses less resources than a pipe, as it only needs to store a
single 64-bit integer, as opposed to a full buffer.
It was introduced first on Linux version 2.6.22 and glibc 2.7. However,
both the configure-time test and the runtime usage require the use of
EFD_CLOEXEC for thread-safety, so this code will be enabled only for
Linux 2.6.27 and up as well as glibc 2.9 and up.

This allows us to have different flags for the compilers for
supporting the same feature. For example, the official flag in GCC to
support AVX2 is -mavx2, but ICC does not support it (yet), requiring
-march=core-avx2 or -xCORE-AVX2. That flag, instead, enables support
for all the features that the "Core-AVX2" processor (codename Haswell)
will support. And clearly, the MSVC flags are different.

Some versions of the DirectFB headers are unclean and will cause Qt

patch.
The compile error was:
qurlquery.h:169:5: error: ‘typeof’ was not declared in this scope
(qplatformcursor_qpa.h includes qevent.h which includes qurl.h which
includes that)
The error comes from the Q_FOREACH expansion. Note that Q_FOREACH uses
__typeof__, so it's supposed to be safe, unless someone ill-advised
goes and defines the GCC "safe" macro (double underscores on both
sides) to something else.

For some reference platforms and SDKs we will need to pass in
extra paths. Currently users have to modify the mkspec to adjust
paths or set environment variables that will be picked up.
This change introduces the -device <name> and -device-option
<key=value> option. The key value pairs will be written to a
qdevice.pri and can be used by the qmake.conf of the device spec.
The reason to not save the key value pairs in qconfig.pri is
becase of the fact that the device spec loads the qdevice.pri
earlier than the qconfig.pri. qdevice.pri allows the mkspec
to set the compiler flags and qconfig.pri allows configure to
add to those compiler flags.

Do not write Q_BYTE_ORDER to qconfig.h in the configures. Instead,
we #define Q_BYTE_ORDER in qprocessordetection.h, since many CPUs only
support a single endian format. For bi-endian processors, we set
Q_BYTE_ORDER depending on how the preprocessor sets __BYTE_ORDER__,
__BIG_ENDIAN__, or __LITTLE_ENDIAN__ (instead of using a compile test
to do so).
For operating systems that only support a single byte order, we can
check for Q_OS_* in addition to the preprocessor macros above. This is
possible because qprocessordetection.h is included by qglobal.h after
Q_OS_* and Q_CC_* detection has been done. Do this for Windows CE,
which is always little- endian according to MSDN.

impossibility. It is unknown whether other compilers provide ARM FPA

should the need arise, but since ARM VFP is available for ARMv5 and up,
we should encourage implementors to instead use soft-floats or VFP.
