This is a completely different error message, and it points out a real
problem, which has nothing to do with building in a separate
directory.  The problem is triggered by --without-all, which includes
 --without-modules, and that causes us not to compile dynlib.c, which
is needed by the tree-sitter support.

I installed a fix on the emacs-29 branch.  The patch is below if you
want to try it before it gets merged to master.
