The testsuit for qemu is broken in some ways. To start with the Makefile is broken, so make test seems to do nothing on any other acrh then i386, on x86_64 it just fails. The files to make it work are there, but the Makefile cannot just handle. It also seems to only try i386-linux-user... So in short: qemus testcase will fail if you do not compile i386-linux-user and are running i386 and should be RESTRICTed until upstream gets better at doing Makefiles.
No longer in tree.
