--enable-final should only set the -O1 linker flag, dunno why libtool
should care for that.

Anyway, extracting the dlname from the libtool archive doesn't sound
like the best solution either. IMHO, it would be better to place only
the basename plus the path of the module into the .desktop file (i.e.
use "actions" for "libactions.so") and let the panel figure out the name
using g_module_build_path().
