R 4.0.0 rebuild status

Thanks for starting off builds. However, please be careful merging to
master, as some packages were bumped and have incompatibilities that
should not be put in stable releases. I will try to come up with an
exact list soon.

I am doing the process manually to ensure that this does not happen.

Basically my method is for a given package called appropriately pkg:

cd R-pkg
less R-pkg.spec # read file to ensure that it is safe to build it

if it is safe then I run:

$ fedpkg switch-branch f32 && git merge master && git push && fedpkg build --
target=f32-build-side-24797 && fedpkg switch-branch master; cd ..

the idea, of course, is that if the merge fails then the case needs to be 
dealt manually.

FWIW most of the credit goes to Tom (spot) since the heavy lifting was already 
done. :-)

I will welcome your list as it becomes easier to find those cases. As I said 
before I am doing my best to avoid those cases.
