Adding specialHTMLTargets to EXPORTED_RUNTIME_METHODS carries the
obligation to actually use it as well; failing to do so makes Emscripten
stop with a reference error on startup.
However, we can't guarantee that Qt will use it in all cases. The
current usage depends on QGuiApplication being used. Application code
could be using QCoreApplication, or no application object at all.
Detect if specialHTMLTargets is present instead, and then enable the code
paths which uses it if that's the case. This means that apps which want
to use e.g. multiple browser windows can opt into support by making sure
EXPORTED_RUNTIME_METHODS contains specialHTMLTargets.

According to latest clang source code (llvm-14.0.3) non-fragile ABI
is default for everything but i386 which means we can stop passing the
-fobjc-nonfragile-abi option.
See
https://github.com/llvm/llvm-project/blob/llvmorg-14.0.3/clang/lib/Driver/ToolChains/Darwin.h#L245
This gets rid of the following warning when building a qmake project
for iOS, while targeting the iOS simulator:
clang: warning: argument unused during compilation:
'-fobjc-nonfragile-abi' [-Wunused-command-line-argument
It only happens for the simulator case because Xcode adds the
-fobjc-abi-version=2 option, thus the qmake one gets ignored.
As a drive-by also remove the usage of the -fobjc-legacy-dispatch
option. According to clang sources it should be implicitly used
on iOS.

JavaScripts's BigInt feature provides support for arbitrary-precision

The -mno-direct-extern-access tells the compiler and linker that
references to symbols outside this ELF module mustn't be direct and must
instead always go through the GOT or PLT (the PLT can additionally be
disabled with -fno-plt). The ELF protected visibility tells the compiler
and linker that this symbol is present in the dynamic symbol table as an
export, but it cannot be interposed by another ELF module.
This option is required for user code to link properly to Qt, otherwise
they will get linker errors (assuming GNU binutils >= 2.39) or runtime
failures (glibc >= 2.35). Both versions of glibc and binutils are older
than GCC 12, so it's a safe assumption they are in use and downgrading
the toolchain or libc is not supported. Adding this option to the
compilation is assured for CMake and qmake-based projects.
For example, all accessess to QCoreApplication::self in QtCore, after
this change and with GCC 12 are relocation-free and direct:
000000000013ebf0 <QCoreApplicationPrivate::checkInstance(char const*)>:
13ebf0: cmpq $0x0,0x4f73d0(%rip) # 635fc8 <QCoreApplication::self>
13ebf8: setne %al
13ebfb: je a90fe <QCoreApplicationPrivate::checkInstance(char const*) [clone .cold]>
13ec01: ret
Meanwhile, accesses to the same variable in other modules are indirect
via the GOT:
66650: mov 0x876e1(%rip),%rax # edd38 <QCoreApplication::self@Qt_6>
66657: cmpq $0x0,(%rax)
This replaces the -Bsymbolic and -Bsymbolic-functions (broken)
functionality that Qt has been using or attempting to use since ~2006.

When building a shared library (with qmake) in a user project
targeting Android, the library gets a QT_ARCH suffix added to its
name.
This suffix is not added when building a static library
(CONFIG += staticlib).
In the context of a multi-abi android qmake build, all the arch
specific static libraries would have the same name and would
override each other.
This happens with Qt 5.15 and it would also happen in Qt 6,
but we don't support multi-abi qmake builds in Qt 6 so far.
When the original fix to include the arch suffix for shared libraries
was done in Qt 5, d463a63bb9
it was likely an oversight that it was not applied to static
libraries as well.
The !static part of the condition was added in
72d4f0750b .
The change only handled installation responsibilities, not naming of
libraries.
Fix static libraries to include the arch suffix, but only in Qt 6.
It's too late to fix it in Qt 5, there might be projects that rely on
there not being a suffix in static library names. Adding the suffix
would suddenly cause linking errors.
