[PATCH] Make compilation of preloaded module glue -Wstrict-prototypes clean

[Lennart Poettering]

When generating the glue code for preloaded modules libtool produces
invalid prototypes without argument lists. When compiling with
slightly fascist compiler options (-Wstrict-prototypes) this has the
effect of causing gcc to print gazillions of warnings when the final
libtool call is done -- for each symbol one.

The fix is trivial. The prototypes should have an argument list of void,
not empty.
