This commit removes USR_PREFIX and introduces ETC_PREFIX instead. The purpose of PREFIX is the installation prefix in the system, not the installation destination. The latter one is what DESTDIR is used for. This should clear up the confusion. PREFIX was already mis-used as installation destination. But that doesn't mix well with how the make targets are designed. CC: Timofey Titovets <nefelim4ag@gmail.com> Signed-off-by: Kai Krakow <kai@kaishome.de>
