This commit adds the `-device` and `-device-option` flags necessary for cross compilation to `configureFlags`. It also adds the (one-entry at the moment) Rosetta Stone for QT-5 as a `let`-defined `qtPlatform` function which takes a nixpkgs platform and returns a QT-5 `mkspecs`-string.
This commit: - sets the `PKG_CONFIG_SYSROOT_DIR` and `PKG_CONFIG_LIBDIR` environment variables when compiling a cross-targeted `qmake`. This is required; if these environment variables are unset, `qmake` won't even try to use `pkg-config`. - writes `LDFLAGS`, `CFLAGS`, and `CXXFLAGS` into `qmake.conf`.
