Cool, glad to know the recent changes made by Waldemar improved things.

Yeah, for basic things. But we had to deprecate them because they are
causing way too many build issues with a significant number of packages.

Seems like musl only supports 'microblaze', which is the BE variant of
Microblaze. I'll send a patch to adjust the Buildroot dependencies to
not offer the MUSL external toolchain on microblazeel.

Thanks a lot for the report!
