KLEE does not compile on 32bit architectures.
This bug appears to have been reported against 'rawhide' during the Fedora 35 development cycle. Changing version to 35.
KLEE now targets x86_64 exclusively.
Per https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org/message/4OMGU5X2W4IHXSEYYJDLRGZRVSE5KDAV/ the aarch64 tracker should not be used anymore (packaging guidelines is being updated)
The package was retired in rawhide.
