sh: Fix linking of ms7722se

While it is true that we no longer have 'ppcenv' and similar sections,
including env/embedded.o at all results in the text/etc sections being
available for the rest of the link.  This in turn is required for the
setup used on ms7722se.  This also, likely, needs further fine-tuning.

Fixes: f40ad66fa0 ("arch/sh: don't bring common/env_embedded.o into the link")
