Read it as 'Build conditionally without' - so only if somebody passes
--without to the build process, it will be built without. The default
behaviour is 'with' in this case.

This is not important to the fix, but I'm still trying to grok the syntax.


Note that with:

%bcond_with protobuf_python

no python binding subpackage is built.

While with:

%bcond_without protobuf_python

a python binding subpackage is built.


That seems like there is double negative logic in place and only the
first negative is reflected in the above.

Is this a specific double negative logic implementation in
protobuf.spec, or is bcond always used with a double negative type
logic.
