I took a look at pypy3, and I see we already define pypy3 variants of
the python3 macros... Do we want to deduplicate them and maybe have a
macro switch for flipping the interpreter? In that case, then
pypy3-devel should BR python3-rpm-macros...
No idea. I don't think that it is needed, I'm just saying it is possible.
