+- `qemu` sets additional variables for the `cmake` and `meson` build styles to allow
 executing cross-compiled binaries inside qemu.

+- `qmake` creates the `qt.conf` configuration file (cf. `qmake` `build_style`)

+This aims to fix cross-builds for when the build-style is mixed: e.g. when in a

+`gnu-makefile` style, respectively.
