Sync with changes from upstreams
Create missing document_pdf.svg, build fails without it.
Built for x86_64 with PGO with zram trickery mentioned in https://pagure.io/abslibre/pull-request/89
Didn't try to build on i686 and armv7h, also didn't check if there were any updates from their upstreams, sorry for that.
