The Intel whitepaer[1] recommends using the RDSEED over RDRAND whenever
present. libstdc++ from GCC 10 will also use it in std::random_device.
[ChangeLog][QtCore][QRandomGenerator] The system() random generator will
now use the RDSEED instruction on x86 processors whenever available as
the first source of random data. It will fall back to RDRAND and then to
the system functions, in that order.

The requirement to separate debug and release DLLs on Windows stems from
the Visual Studio C run-time library appearing in two different variants
(debug and release) and not mixing well. It's possible to perform builds
without optimzations and with debug symbols while linking against the
release version of the C run-time, but at the same time the debug
version of the run-time brings other developer visible advantages.
MinGW on the other hand does not have this distinction, does not ship
with separate DLLS and does also not require the VS C runtime library.
Therefore we do not need this separation for MinGW, which means that our
packages can be reduced in size and application developers wishing to
debug their applications do not have to use debug builds of the Qt
libraries or run into Qt internal debug code.

For nmake and VS projects we added the NDEBUG define for the release
configuration unconditionally within the qmake generators. To undefine
it, users had to use a nasty work-around.
Now, define NDEBUG within the MSVC mkspecs. In order to do that we
introduce the DEFINES_RELEASE and DEFINES_DEBUG variables that are
merged into DEFINES in default_pre.prf.
Users can unset NDEBUG by writing
DEFINES -= NDEBUG
in their .pro file.
Note that DEFINES_RELEASE and DEFINES_DEBUG are merged in
default_pre.prf in order to give extra compilers (like moc) the chance
to see the fully resolved DEFINES variable. This is different from the
QMAKE_CFLAGS_(DEBUG|RELEASE) variables that get merged in default_post.prf.

This reverts commit 521a85395d.
Having libraries resolved to absolute file paths by configure has
annoying consequences:
1. The Qt installer needs to unabsolutify paths in all kinds of files.
This is error-prone and fragile.
2. It hurts Qt's relocatabilty. The absolute paths are unlikely to be
right on different systems.
3. Qt's configure must imitate linker behavior correctly to do the
resolution right on every platform, which is hard to get right.
Consequently, the disadvantages of 521a8539 outweigh the advantages.
