50e664835b Fix linking of debug projects against release Qt on Darwin platforms
Consider a release-only, non-framework Qt build on macOS.  Building a
debug user project would fail, because qmake tried to link
against *_debug.dylib and *_debug.a libraries.

Building a debug user project that uses QtUiTools against a release-only
framework-build Qt posed the same problem.  QMake tried to link against
the libQt5UiTools_debug.a, which does not exist.

Fix this by maintaining a list of library file candidates, and use the
first existing one (or just the first one if none exists).  This favors
the library matching the user project's configuration but falls back to
the release version of the library if necessary.

f9c850cc42 qmake: Pick default architecture on macOS based on uname
When dealing with a universal build of Qt, we would end up
using the QT_ARCH as the architecture for user projects,
but this architecture is always the primary one that Qt
was configured with.

Instead of relying on QT_ARCH, we start writing QT_ARCHS
(plural) to qconfig.pri, based on CMAKE_OSX_ARCHITECTURES,
and then use that to initialize QMAKE_APPLE_DEVICE_ARCHS.

We then resolve the active arch using uname -m, matching
what CMake does.

We still feed all the available architectures to the
Makefile or Xcode project, so that the user can build
for any of the available architectures without needing
a reconfigure.

9082cc8e8d macOS: Don't hard-code x86_64 as the architecture when using qmake
The qmake variable QMAKE_APPLE_DEVICE_ARCHS was added for iOS,
to support universal builds, as the QT_ARCH is a single value.

Since the qmake macOS builds are non-universal (at the moment),
we remove the hard-coded value for QMAKE_APPLE_DEVICE_ARCHS on
macOS, and let the normal architecture test resolve the arch,
like on other platforms.

To ensure that the following configuration tests are run with
an -arch argument, we trigger a commit of the preliminary Qt
configuration after running the architecture test. This is not
strictly necessary, but makes it clearer what's going on during
configure.

The device_and_simulator configuration option was used by the
iOS toolchain, and needed to be moved up in the configuration
test order to not break later tests.

The logic in mac/default_post.prf for both Xcode and Makefiles
to add -arch flags was kept as is, based on the existing
variable, to avoid too many changes to this logic.

The logic in toolchain.prf was amended to make it clear and
ensure that it only applies to iOS builds. macOS builds do
not have this issue.

ff170962d4 Don't rely on the module.pri for the entrypoint linking to the library
Depending on the presence and behavior of HEADER_MODULE/header_module
in CMake and qmake land, the module.pri might end up with an empty
module line, which means adding the module via QT_PRIVATE += entrypoint
will not link to the static library.

To avoid this problem we write an explicit module entry (QT.foo.bar)
into the same module.pri file as the one generated by qt_module,
where the auto-generated one has header_module enabled, and hence
no link behavior, while the manually written entry has a module
component, and will ensure linkage to the static library.

4940f6d04c CMake: Remove old Qt 5 CMake build system files
Remove the stale Qt 5 CMake files.

Disable the generation of CMake files by the qmake build system,
it wouldn't create usable Qt 6 files anyway.

Keep mkspecs/features/create_cmake.prf and
mkspecs/features/cmake_functions.prf for now until we can confirm that
they are safe to remove.

5c1ed8bb74 Use 'A' for Apple framework version instead of Qt major version
All system frameworks use 'A' instead of the major version of the
framework, and Xcode's code signing assumes that the framework version
is 'A' when signing embedded frameworks (FB7323980), so leave the
version 'A'. This is also what Apple recommends.

ac43986aa5 Pass -arch when running toolchain configure test on Apple platforms
Clang doesn't automatically switch architecture just because we're
passing an iPhoneOS sysroot. In the past this resulted in a warning
about trying to link an x86_64 binary to arm64 libraries, but with
Xcode 12 this is now a hard error.
