[Buildroot] Is there any plan for supporting Qt6

[Andy Yan]

Hello:
      Buildroot is a great project, it gave me many convince for building embedded rootfs. 
      I found Peter has submitted Qt6 support at the early of 2021[0], but it seems this series has
not bee merged yet. May i Know if there is any further plan for Qt6 support in buildroot?
