REAL_* are sure use in install/deinstall scripts and the other uses
outside the build process. REAL_ROOT_USER has a special use case for su
as well. Basically, the way the unprivileged overrides "fix" most of the
issues is to just substitute the user/group of the current user into the
Makefiles. This works fine for things like installing files, but doesn't
work well for rc scripts etc. This makes a huge difference if not all
groups are currently active or if you are using DESTDIR installation as
unprivileged user.
