I meant (said?) predefine, not hardcode (it was hardcoded the last few years :-).

Summary of wishes:
- configure checks if users sets a share path with --with-proj-share=
- if not PROJSHARE is predefined to path derived from PROJLIB
- then configure checks if the path (be the predefined, be the user selected)
  exists
- configure sets PROJSHARE accordingly

Current state:
- PROJSHARE is undefined
- if --with-proj-share is not used (which is normal) then PROJSHARE remains
  undefined. Here a solution is needed, it should derive the path from the
  PROJLIB setting

We "just" have to figure out how to extract the path from the PROJLIB settings,
then use this unless the user enables --with-proj-share=
