trees: err if target.cfg not given if multi-tree

it was always by design that an error should occur, if a
target.cfg file does not exist on multi-tree projects,
but we previously did not support target.cfg files on
single-tree projects.

single-tree target.cfg support was later added, and it was
done by making target.cfg optional there, but i accidentally
made it optional on multi-tree projects.

in practise, all multi-tree projects included target.cfg,
but this was not being enforced in code.

this patch should fix the issue.
