Thanks for testing! :-)

My build eventually finished successfully here too, with just the
strictly minimum to enable wireshark and GUI stuff:

    BR2_arm=y
    BR2_cortex_a7=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_INIT_NONE=y
    BR2_SYSTEM_BIN_SH_NONE=y
    # BR2_PACKAGE_BUSYBOX is not set
    BR2_PACKAGE_QT5=y
    BR2_PACKAGE_QT5BASE_LICENSE_APPROVED=y
    BR2_PACKAGE_QT5BASE_GUI=y
    BR2_PACKAGE_QT5BASE_WIDGETS=y
    BR2_PACKAGE_QT5TOOLS=y
    BR2_PACKAGE_WIRESHARK=y

Then wiresharkd reports:
