The $output program cannot be directly executed until all the libtool
libraries that it depends on are installed.
This wrapper executable should never be moved out of the build directory.
If it is, it will not operate correctly.
Currently, it simply execs the wrapper *script* "$SHELL $output",
but could eventually absorb all of the scripts functionality and
exec $objdir/$outputname directly.
