However, that's still not an argument for a downgrade of the toplevel copy
of "missing" to an older version. We can't possibly match toplevel
scripts to subdirectories not shipped with GCC, since we want to support
multiple versions of libraries such as GMP, which may each require a
different version of such a script if the script makes incompatible
changes; we can only ensure that they get configured in ways sufficiently
isolated from GCC itself.
