Update to allow build on Pi5

Can the Dockerfile be updated to allow Pi5 builds?

```
    cd log4cpp && \
--
    wget -O config.guess 'https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD' && \
    chmod +x config.guess && \
--
    ./configure --prefix=/usr && \
```
