Yes, exactly. I've always built git like this:

  $ make prefix=/usr/local/stow/git
  $ sudo make prefix=/usr/local/stow/git install
  $ cd /usr/local/stow
  $ sudo stow git

It works for all other programs I've tried too (most of which only require me to specify the prefix once, with ./configure --prefix=...). The programs never need to know about the symlinks; they're only there for when other programs need to access them (via PATH, etc.).
