I tried to contact upstream, but they don't accept pull requests:

- https://github.com/gerbv/gerbv/issues/244
- https://github.com/gerbv/gerbv/pull/226#issuecomment-2566103734

So it can only be done here. I updated initial patch with suggested
configure flags and commented why git is added to native inputs.
