These (replacement #f) fields should not be needed.  'replacement' is
now an 'innate' field of the package record type, which means that it is
not inherited.

We seem to be oscillating on the question of whether to graft these
early GLIBCs.  In June 2017, I switched to using 'package/inherit' here
in commit 13f7f2fd2b208c29361ef2290f55911879a6adf2, and in October those
changes were reverted in commit 848f550f2c105326dc3be4033c8aaf35ec21cde4
by Efraim, although I'm not sure why.

It'll be painful to have *everything* grafted until the next
core-updates cycle, but I suppose it's necessary.

      Thanks,
        Mark
