Miyoo Mini build no longer completes

[Trihedraf]

Since #6484 the Miyoo Mini build can't complete on master due to the toolchain using gcc8.

I made an issue on the toolchain's GitHub to see if we can get an updated release with a newer gcc

... was it not ready for merge?

This is a separate issue. The other part is good and works for 1.5.3. This is just something that will need to be fixed before 1.6 comes out or we won't have a miyoo mini release.
