Fons - you don't! DESTDIR is empty by default. Hence "make install"
installs directly for a regular user who has not bothered to set it.
PREFIX is the way that a non-packaging user targets the install to
somewhere other than the default, no matter what "the web page about
DESTDIR says". DESTDIR is strictly for packagers/developers, and
merely has to be supported by the makefile, not used by a "regular
user".

The reason for having two distinct variables is that some software
needs to know PREFIX at compile time (e.g. where to find conf files,
or private shared libraries, etc). If the packager is aiming to
install the software in /foo/bar eventually, then she needs to set
PREFIX appropriately. But they may want to use /baz/bomb as a "staging
ground" for packaging, hence DESTDIR. Again, this does not affect
"regular users", who simple set PREFIX (if anything at all).
