iasl has long been broken on big-endian, but it has also long contained
code that simply makes it exit immediately in that case, and qemu copes
with that. So if there's buggy iasl it would be a distro which removed
this big-endian check and tried to make it work on big-endian but failed.
Fedora tried the latter, but at least in rawhide it works properly now.
I'm unclear if we shipped broken iasl with the BE check removed in stable
versions though
