Unfortunately not, since the wildcard doesn't match anything:

    $ ls -1 ../src/.libs/libvirt*
    ../src/.libs/libvirt.a
    ../src/.libs/libvirt.la@
    ../src/.libs/libvirt.lai

If you want to try to reproduce it yourself, do this:

  ./configure --disable-shared && make

Without my patch, I get results like this on rawhide:

I'll see what happens with profiling.
