Add working example and test case for diesel
Fixes #27, or at least works around it. This deals with the issues mentioned in https://github.com/sgrif/pq-sys/pull/18, and it relies heavily on ideas from @golddranks and @clux.

## Adding more C libraries
|

|

If you're using Docker crates which require specific C libraries to be

installed, you can create a `Dockerfile` based on this one, and use

||||
`musl-gcc` to compile the libraries you need. For example:

If you're using Docker crates which require specific C libraries to be installed, you can create a `Dockerfile` based on this one, and use `musl-gcc` to compile the libraries you need. For an example, see [`examples/adding-a-library/Dockerfile`](./examples/adding-a-library/Dockerfile). This usually involves a bit of experimentation for each new library, but it seems to work well for most simple, standalone libraries.
|
||||
|
||||
```Dockerfile
|
||||
FROM ekidd/rust-musl-builder
|
||||
|
||||
# EXAMPLE ONLY! libz is already included.
|
||||
RUN VERS=1.2.11 && \
|
||||

|
||||

||||
make && sudo make install && \

||||
cd .. && rm -rf zlib-$VERS.tar.gz zlib-$VERS
|
||||

||||

||||
This usually involves a bit of experimentation for each new library, but it

||||
