No, if one follow the directions in "* Building Emacs with tree-sitter"
it will fail, well-configured system or not as long as you consider
"/usr/local/lib" as a wrong place to install tree-sitter.  I just remind
you that it is tree-sitter itself with make+make install that install
tree-sitter libs in this place.
I just say that for people trying to install tree-sitter, if it just for
me I am fine with "--without-tree-sitter".
