Please do that on per-arch basis. For instance, pie support tends to
be broken quite often on mips (afaik, it's currently broken on debian
unstable). I know qemu doesn't support mips host but it doesn't mean it
will never be supported - I need to find time to update to current git
and fix remaining bugs in my code before sending it for merge.
Unfortunately, this kind of patch will make sure it won't happen soon :(


Thanks,
Arnaud
