I have there /usr/share/proj/epsg

but even if you can't find it, entering 4326 and proj string
+proj=longlat +datum=WGS84 +no_defs +type=crs

should do it. Then, you have to switch that on in map display settings (see
map display toolbar) -> Status bar -> Display coordinates in different CRS
The idea was to move the epsg panel in GUI settings to the map display
settings, but this part never got finished...
