The one without 'noinst', because this is the one which can yield an
-rpath option.

In tests/libtool8.test you test that the case where two different
installation directories are given for the same library: $(libdir) and
$(pkglibdir). These conflict.

In the case I'm presenting, it's different. There is no $(noinstdir).
One specification gives no installation directory, and the other one
gives 1 installation directory. 0 + 1 < 2. There is no conflict.

Here is this definition: Take the list of prefixes, remove duplicates,
then remove "noinst". Then if more than 1 remains, it's an error.
