Recording and hard-coding configure-arguments is a silly idea, because
configure-arguments only have a meaning to a local source tree.

They are meaningless to anything outside of the particular sources,
because a library package (such as RTEMS) has no knowledge about what
infrastructure users might be using.

No - Nobody needs this kind of information.

What people need is information on "features a package has built-in".

Correct, it's temporary and so are configure-arguments - They should not
be of interest to anybody.
