I have seen the failing builds and according to root.log, the issue is pandoc. I need to check the state of pandoc in rawhide, but it's only used to build the man page for shellcheck(1). I could temporarily build put a pre-built man page in the srpm if it doesn't go against the guidelines, this way we could have shellcheck(1) on ARM too.
Now that bug 992430 is fixed, it builds! http://koji.fedoraproject.org/koji/buildinfo?buildID=521908
