LX2160A cannot self-host build debian 12 flex-build

I am buildig the latest flex-build from github.

By cross-compiling via docker, I managed to build an image.

However, when trying to build the same image of flex-build on the LX2160A itself, I get the error after a while:

Confirmed with the LSDK development team.

Building debian on the target board is not supported.
