Merge #21655: build, qt: No longer need to set QT_RCC_TEST=1 for determinism
c799a19b4bb8d0cc5ffd9b49746b5b267745c9b5 build, qt: No longer need to set QT_RCC_TEST=1 for determinism (Hennadii Stepanov)
Pull request description:
The Qt Resource Compiler (rcc) output order relies on [`QHash`](https://doc.qt.io/qt-5/qhash.html):
> This randomization of `QHash` is enabled by default. Even though programs should never depend on a particular `QHash` ordering, there may be situations where you temporarily need deterministic behavior, for example for debugging or regression testing. To disable the randomization, define the environment variable `QT_HASH_SEED` to have the value 0.
Since #3620 we use `QT_RCC_TEST=1` to achieve a deterministic output.
Since Qt 5.3.1 hash seeding is disabled for all of the bootstrapped tools, including rcc. Therefore, `QT_RCC_TEST=1` is no longer needed.
See commit [5283a6c87beac5a43f612786fefd6e43f2c70bf6](https://github.com/qt/qtbase/commit/5283a6c87beac5a43f612786fefd6e43f2c70bf6).
