[PATCH] scripts: bareboxenv: add erase hint if build as host-tool

[Marco Felsch]

The bareboxenv behviour is different if used as host-tool. As host-tool
the erase is skipped which can confuse the user. Add a help note as hot
fix. In the long term we should add the host-tool erase support as well.
