Changes v1 -> v2:
  - update most font licenses (thanks to Arnout Vandecappelle)
  - add comma-separator between the licenses (no nice solution,
    will add ' ,', but without the starting problem at:

    QT_LICENSE = LGPLv2.1 with exceptions or GPLv3
    ifneq ($(BR2_PACKAGE_QT_LICENSE_APPROVED),y)
    QT_LICENSE += or Digia Qt Commercial license
    endif
