--- Comment #8 from Paolo Bonzini <bonzini at gnu dot org> ---
No, I cannot...  The .lo file is something like this

# trace/generated-tracers.lo - a libtool object file
# Generated by libtool (GNU libtool) 2.4.2
#
# Please DO NOT delete this file!
# It is necessary for linking the library.

# Name of the PIC object.
pic_object='.libs/generated-tracers.o'

# Name of the non-PIC object
non_pic_object='generated-tracers.o'

The format and location of the objects is internal to libtool.  Also, QEMU uses
a pre-installed libtool (because QEMU is not autoconfiscated) so I cannot add a
special-purpose DTRACE tag.

Note that this will be mostly a problem with downstream distributions, since
upstream we're dropping this usage anyway for unrelated reasons (we do not need
to put generated-tracers.o in a library anymore).  I guess one could hack the
dtrace script around in downstream systemtap.

Thanks for the discussion!
