BUG: Makefile dependencies are not correct for tools using libwandio

when doing make -j9 (using 8 parallel cores to build) the build will fail trying to compile  ```wandiocat``` and maybe others that depend on libwandio - because libwandio was not created yet.
this could be fixed by making libwandio.la a dependency of wandiocat (and possibly other tools requiring the lib).

i'm using this bogus pull request to report the issue, since you disabled the github issue tracker and i cant be bothered to register at yet another mailing list or proprietary bug tracker.
i cant even be bothered to search its URL.
