[BUG] GD32 MFL cannot build without U8glib update

[bmourit]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

The initial support for GD32 that was merged had the pull request in the U8glib repo linked in, so I'm not sure if it was intentionally merged anyway without it - perhaps pending LCD changes? If so, this can be closed. If it was just accidentally missed, then that repo has the feature request and patch already requested. I'm only creating the bug report here since Marlin wont build without the changes.

Progress! I see this was merged, so now we'll just wait for the new package to be released. Awesome! And thank you!

EDIT:
The only thing preventing building is in features.ini
HAS_MARLINUI_U8GLIB = marlinfirmware/U8glib-HAL@0.5.4

While the code was merge, this still is using the last release to build. Just wanted to mention that in case it got missed. If this is known and intentional for now, just ignore this. 🙂 Otherwise bumping the release, for example to U8glib-HAL@0.5.5, will likely be required. This isn't something I can do or patch though.

If you change that to the following it uses latest code vs latest release
HAS_MARLINUI_U8GLIB = https://github.com/MarlinFirmware/U8glib-HAL/archive/refs/heads/master.zip
