Correct. It doesn't matter that they don't exist,
they are just *potential* search directories and
if you feel like cleaning that up you can.
This is all part of the sysdeps machinery that creates
a list of ordered search directories for headers
and files to install.
You're now getting into the technical details of
the sysdeps and Implies build machinery that are part
of the glibc build system.
Any notes you want to make on the wiki would be more
than appreciated as they would serve to help other
