I'm on Arch Linux and I don't have the environment variable
$XDG_DATA_DIRS set. I only have a $XDG_RUNTIME_DIR set by systemd.
I get that setting from python-xdg, from this code snippet:
_home = os.path.expanduser('~')
xdg_data_home = os.environ.get('XDG_DATA_HOME') or \
os.path.join(_home, '.local', 'share')
xdg_data_dirs = [xdg_data_home] + \
(os.environ.get('XDG_DATA_DIRS') or
'/usr/local/share:/usr/share').split(':')
It seems that it's getting a default value, but with one more than the
Freedesktop.org spec.
I've checked the source of the awesome window manager, it always uses
a similiar default path list, but /usr/local/share comes last (maybe this
should be fixed).

However, it seems to me that $prefix/share/applications is a good
default if the script is going to install .desktop files, rather than
check $XDG_DATA_DIRS and pick one up. The user can move / link the files
if necessary, or perhaps another ./configure option?
