In commit 9f6b9e28ccfdc3a96fb6e28d5121539f3cba3c55 the steps for putting out a new Tor release changed from running `make check` to `make distcheck`. With this change there is no need for the dist rule in Makefile.am:76 anymore. The rule causes Tor to be built and tested twice when `make distcheck` is called (once in the current build directory and other time in the temporary distcheck build directory). This is caused by the `distcheck` rule calling our `dist` rule which calls the internal `check` rule which triggers the `all` rule. The removal would make the workflow of testing build configuration changes faster (especially on slower machines) by not having to wait on the first compilation and testing phase which is performed by distcheck anyway.
