The prefix option is (only) used to setup the lispdir (where all
lisp-files go) and the infodir (where the manual goes).  Thus it's
about where you want Org mode to be installed to -- by default Org is
installed system-wide in

+-$prefix-+-$lispdir-----------+
|         |                    |
v         v                    v
/usr/local/share/emacs/site-lisp

If you, for example, want to install Org mode to your homedirectory
you could ignore the prefix option and set lispdir and infodir directly.

,----
| lispdir = /home/<user>/.emacs.d/site-lisp
| infodir = /home/<user>/.emacs.d/info/
`----

PS: And you don't even have to modify the Makefile.  Passing the
variables (lispdir, infodir) as command line arguments to make works fine.

E.g.: 

,----
| make lispdir=/home/dmaus/.emacs.d/site-lisp/org-mode/ infodir=/home/dmaus/.emacs.d/site-lisp/info/  install
