Why did you build with ns-self-contained disabled?  AFAICT from
reading the top-level Makefile.in, this causes Emacs to install files
according to Posix conventions, which breaks on macOS.  What you get
is the Emacs binary in a place unrelated to the directory where the
*.eln files are installed, and Emacs cannot find them.

You could perhaps set ELN_DESTDIR explicitly when you run "Make", as
in

   make ELN_DESTDIR=/Users/merrickluo/projs/emacs/nextstep/Emacs.app/Contents

Maybe.
