+Option to constrain linux-user exec() to emulated CPU only
+
+When trying to reproduce a bug someone reported on an actual AMD K10[1], ​I tried to directly throw `qemu_x86-64 -cpu 
+​phenom path/to/wrongly-labelled-instruction-set/gcc 1.c` at the problem, but failed to get an "illegal instruction" as expected. A quick investigation reveals that the error is actually caused by one of gcc's child processess, and that the said process is being ran directly on the host. A similar problem happens with trying to call stuff with /usr/bin/env.

+
+Since both the host and the guest are x86_64, I deemed binfmt inapplicable to my case. I believe that QEMU should offer a way to modify exec() and other spawning syscalls so that execution remains on an emulated CPU in such a case. Call it an extra layer of binfmt, if you must.
+
+The QEMU project is currently moving its bug tracking to another system.
+For this we need to know which bugs are still valid and which could be
+closed already. Thus we are setting the bug state to "Incomplete" now.
+
+If the bug has already been fixed in the latest upstream version of QEMU,
+then please close this ticket as "Fix released".
+
+If it is not fixed yet and you think that this bug report here is still
+valid, then you have two options:
+
+1) If you already have an account on gitlab.com, please open a new ticket
+for this problem in our new tracker here:
+
+    https://gitlab.com/qemu-project/qemu/-/issues
+
+and then close this ticket here on Launchpad (or let it expire auto-
+matically after 60 days). Please mention the URL of this bug ticket on
+Launchpad in the new ticket on GitLab.
+
+2) If you don't have an account on gitlab.com and don't intend to get
+one, but still would like to keep this ticket opened, then please switch
+the state back to "New" or "Confirmed" within the next 60 days (other-
+wise it will get closed as "Expired"). We will then eventually migrate
+the ticket automatically to the new system (but you won't be the reporter
+of the bug in the new system and thus you won't get notified on changes
+anymore).
+
+Thank you and sorry for the inconvenience.
+
+
+
+This is an automated cleanup. This bug report has been moved to QEMU's
+new bug tracker on gitlab.com and thus gets marked as 'expired' now.
+Please continue with the discussion here:
