Please find attached v2 of the patch updated for trunk 20120706, x86 only, tested on
x86-linux-gnu, KFreeBSD and the Hurd.

I left in the comment about the multiarch names, but I'm fine to change/discard
it. It was first required by Joseph Myers, then not found necessary by Paolo
Bonzini. The patch includes the changes suggested by Thomas Schwinge.

Ok for the trunk?
