In that case I might have to apply the patch to the qemu-xen tree for the Xen 4.4 release before the commit reaches QEMU upstream.

Adjust TMPO and added TMPB, TMPL, and TMPA. libtool needs the names to be fixed (TMPB). Add new functions do_libtool and libtool_prog. Add check for broken gcc and libtool.
