Dear Maintainer,

src:gl2ps fails to build reproducibly because its binary package libgl2ps-doc
vendors a pdf that saves in build date.

Since it does not add any real value to get _Build Date_ into the
documentation, I suppose the cheapest way to get it building
reproducibly is to simply not vendoring such a date in its
documentation.

I'll shortly push this to salsa, and I wish to upload post bullseye release.
I'm pasting the patch below for ref as well.
