This part of debian/rules is already written such qdoc is not build for cross-builds,
so why shouldn't it be possible to disable it for some architectures either?

override_dh_auto_clean:
        dh_auto_clean
        rm -fv .qmake.cache
        rm -fv debian/qttools5-dev-tools.install

build-doc-tools:
        # Build qdoc, qhelpgenerator and qtattributionsscanner tools                                                                                                                                              
        cd src; qmake CONFIG+=disable_external_rpath
        dh_auto_build -- -Csrc sub-qdoc sub-qtattributionsscanner
        cd src/assistant; qmake
        dh_auto_build -- -Csrc/assistant sub-qhelpgenerator

override_dh_auto_build-indep: build-doc-tools
        cd src/qdoc; qmake
        cd src/assistant/help; qmake
        dh_auto_build -- docs

ifeq ($(DEB_HOST_ARCH),$(DEB_BUILD_ARCH))
override_dh_auto_build-arch: build-doc-tools
        # Rebuild the internal assistant.qch which is used as a resource                                                                                                                                          
        cd src/assistant/assistant/doc/internal; qmake
        dh_auto_build -- -Csrc/assistant/assistant/doc/internal docs
        mv doc/assistant.qch src/assistant/assistant/assistant.qch
        dh_auto_build
endif

The actual documentation is only generated in override_dh_auto_build-indep
using the build tools generated in build-doc-tools. But if we're not
building any documentation in a binary-arch build, why should we build
the documentation tools either?

For openjdk-X, the documentation is generated using pandoc which isn't
available on every architecture either, yet the binary-arch target of
openjdk-X builds on every architecture.

So, I'm convinced the problem can be solved with better packaging.
