There isn't one. It's simply a placeholder, empty by default, and is
only used during "make install" to redefine where the installation
should be rooted. That way, instead of doing just "make install" I
can do "make install DESTDIR=/mnt/chroot_or_remote_filesystem" and the
installation will proceed as normal except into a filesystem anchored
at that point. It could be a chroot jail, or an RPM buildroot, or a
remote filesystem, or whatever.
Basically, every "install" rule has its target directory prefixed with
$(DESTDIR), so instead of installing into $(bindir), you install to
$(DESTDIR)$(bindir). Since it's empty by default, nothing changes
unless you set it to something. Most packaging systems need to
install files into a buildroot or virtual root of some kind so that
it's easy to see what files were installed by the package and package
them up.
Automake does this by default, so there are ample usage examples in
case my explanation wasn't clear. :)
Or, I'm attaching the patch I wrote against epic4 that adds support
for DESTDIR. That might be a better point of reference.
