* Use an older glibc so resulting binaries can run
on older systems (without having to link statically
against glibc)
* Call packages static-compat-* to make it clear that
these packages are intended for compatibility with
older distributions
* Add further libraries to get static-compat-qt6-base
and some other static-compat-qt6-* packages building
* Add mingw-w64-cmake-static as a separate package
* Fix linker errors (FREETYPE_DEPENDENCIES really must include `-lfreetype`
itself due to the cyclic dependency between FreeType2 and Harfbuzz
* Add patch to fix static compilation of qt6-tools
sorry, but I dont see what that is supposed to fix, the actual library name is /usr/i686-w64-mingw32/lib/libvulkan-1.dll.a and is correctly fond by the default findvulkan.cmake
* Add certain variables to find Qt's dependencies to the CMake
toolchain file because these variables would otherwise needed to
be set every time Qt 6 is used
* Add a static variant
* Not fully tested yet
* Further repos besides base and svg will be added later
Initial motivation of adding the flag was better consistency with
compile flags used for regular Arch Linux packages.
However, adding -fstack-protector-strong seems to cause segmentation
faults even before main() is called.
The issue is not reproducible with a simple hello world app and also
not reproducible when launching the app under Linux with WINE. But
a full-blown Qt 5 app crashes in the way described.
