Maybe I'm missing something.  29 packages (out of 166) in ELPA have a
Makefile.  Taking just one random Makefile, company/Makefile, I see


          ${EMACS} -Q --batch -L . -f batch-byte-compile company.el company-*.el

If this Makefile is invoked with "make compile", it clearly expects
Emacs to be found along PATH.  And even if Make is invoked from Emacs,
the directory where the Emacs binary was found is not added to PATH.
So how can this work without Emacs's binary being on PATH?  And what
am I missing here?
