Normally not needed, because $(HOST_DIR) and $(O) are absolute paths, so
there is already a leading '/' .
So:
- I kept a separating '/' in the tests to be extra-ultra sure (but it
arguably could be dropped),
- I did not add that extra '/' in the message so it is nicer when
presented to the user.

Well, it's either duplication of the if-block, or duplication of the
call sites. And I think it is better to have duplication of the
if-blocks, in cas we need to check for mor eloactions, otherwise we'd
have to duplicate even more the call sites...
