change defaults to something that should work on most Linux systems and Cygwin

* default.mk: change prefix to /usr/share and do some formatting

This change establishes the baseline installation path that should work
out-of-the-box on Linux and Cygwin when the install is done system-wide (which
needs administrator privileges).
