[Olsr-dev] change default install location to /usr/local

[Hans-Christoph Steiner]

I would like to include this patch to change the default Linux install location to /usr/local, which is the generally accepted UNIX standard for user-installed programs.  Currently, it installs into /usr, which is set aside for system-installed programs (apt-get, yum, etc.  This patch also includes the standard Makefile variables $DESTDIR, $prefix, and $libdir, for standardized overriding of those locations (i.e. make prefix=/usr).

Any objections?
