- Allow to configure destination directories to fulfill the needs of
different distributions
- Support DESTDIR variable for staging installation when packaging
- Do not set user/group to root. It requires 'make install' to run as
root, but then this is the default behaviour anyways.
Many systems (including Debian, Ubuntu and derivatives like Linux Mint) use
Dash as a noninteractive version of `/bin/sh`, invoked by `make`.
Dash's `echo` command doesn't understand the `-e` option and this generates
spurious output when running `make`. See [a bugreport][0] for one of the
many instances of this bug/feature in action.
