I had the similar issue on ppc64le when trying to package R 4.0.0 for ALT
Linux Sisyphus. Disabling long double support indeed fixes the build of
the binaries, but then the build fails in the tests section (make check)
with violated assertions in some basic tests results.

Do you also have this problem, and is there a better solution to this
issue on ppc64le yet?
