No, I don't think a full rebuild will help here.

On which RaspberryPi are you building ? It's detecting an ARMv7 core
here.

And it doesn't make any sense for ARMv7 to not have support for MLS if
I'm correct.
But more globally, why are you trying to build Buildroot on a
RaspberryPi itself? It's going to be massively slow compared to the
build time you would achieve on any reasonable x86-64 system.
