- remove comment about missing dependencies: they are either not used by
the current configuration (krb5 with system postgresql or nasm with
system libjpeg) or were made to be used in this update (poppler)
- use system fontforge to build opens___.ttf
- use system ucpp as preprocessor
- use system python3-lxml in the build process
- use system poppler and libxml2
- remove outdated libtommath from distfiles
- use vsed everywhere (and remove outdated stuff)
- be explicit about bundling fonts
- use make_build_target instead of make_build_args (more semantically correct)
- patch so build can run in CI
