build: small fixes & enhancementsn-peugnet-add-favicon

- rename LANGUAGE exported env var to LOCAL, not to disturb Make messages
- remove failing sphinx commands
- remove quotes around BUILDDIR and SOURCEDIR as these will never have spaces
- share doctrees for localized builders for perf. This also fixes warning for epub
  about .doctrees unknown mimetype
- fix LaTeX paper size to always use A4
- fix today format to use a localized version
