prefix should be an argument to configure, not make.

make install implicitly includes make all; it is supposed to rebuild
anything that needs rebuilt.

If you want to build locally from a read only nfs mount, then you
should run the configure script in a local directory:

mkdir /tmp/build
cd /tmp/build
/path/to/nfs/source/configure
make
make install

Hrm... Makefile should itself be a generated file from Makefile.in or
Makefile.am, but it appears that git isn't doing this.  Perhaps that
should be fixed.
