Right, this makes sense.

This doesn't make any sense to me:

config BR2_PACKAGE_QT5BASE_EXAMPLES
        bool "Compile and install examples (with code)"
        select BR2_PACKAGE_QT5BASE_NETWORK
        select BR2_PACKAGE_QT5BASE_XML
        help
          If unsure, say N.

Neither BR2_PACKAGE_QT5BASE_NETWORK nor BR2_PACKAGE_QT5BASE_XML are
selecting BR2_PACKAGE_QT5SVG.

Or perhaps it is the line added by your patch:

	select BR2_PACKAGE_QT5SVG if BR2_PACKAGE_QT5BASE_EXAMPLES

which causes this statement ?

This obviously makes sense.
