[R-sig-Fedora] R 4.0.0

[Tom Callaway]

Thinking out loud here... do we want to have some macro magic to embed a
dependency on an R(ABI) provides? Where R 4.0.0 would provide R(ABI) = 4
and all R packages built against it would pick up Requires: R(ABI) = 4 ?
I don't suppose we need it, since the likelihood of someone installing R
module packages but not updating R is low, but I wanted to throw it out
there.
