[Interest] Host Qt version requirement when cross-compiling

[Alexey Rochev]

Does cross-compiling Qt6 (for Android) require exact same version of
host Qt to build correctly? I'm assuming that it does since when I
tried to cross-compile 6.2.2 using host 6.2.3 (don't ask me why) it
failed with a strange error (in cmake_automoc_parser) and it was gone
when I updated the cross-compiled version to 6.2.3. I would still like
to get official information on this, however.
