Nope, the Makefile dependencies would still be wrong, and would
trigger at the wrong times.  Unless I'm mis-reading it.

Remember that, if you configure --disable-static, libtool *won't*
create the .o files, only the .lo object-abstraction files and the PIC
object files inside .libs.  So you want Makefile dependencies on .lo,
not .o.
