How we overwrite configure-commands is currently broken

It should be:

 config:
   configure-commands:
   - |
     %{autogen}
   - |
     %{configure} \
     --disable-static \
     --enable-xkb \
     --disable-xprint

instead

 config:
   configure-commands:
   - '%{configure}  \ --disable-static \ --enable-xkb \ --disable-xprint'

See #27 (closed) for the "always run ${autogen}" part
