I made some minor cleanups to the patch, split it up into multiple
patches, and upgraded my GuixSD system to use it. My system seems to
work fine. I don't have time right now to verify that the grafting is
being done correctly, but I went ahead and pushed the commits to
'master' anyway, based on Leo's preliminary observations.
I'm dubious about the changes made to glibc-2.21, but that can be fixed
up later.
I tried to copy the .drv files for the grafted 'glibc-final' and
'glibc-final-with-bootstrap-bash' from my machine to Hydra, in order to
ask Hydra to build it, but both "guix copy" and "guix archive --export"
failed:

guix archive: error: corrupt input while restoring archive from #<closed: file 17e9d20>
--8<---------------cut here---------------end--------------->8---
I'm concerned that i686 and armhf users are going to have a rude
awakening when they not only have to build two variants of glibc, but
also a bunch of the early bootstrap because the NARs are not available
on Hydra. It would be good if someone could take care of that.
I'm sorry, but I need to sleep now. Hopefully someone else can take it
from here.
