[Lazarus] missing "LCLWidgetType" drop down menu

[Michael Schnell]

Version 1.6 on Windows:

Project -> Project Options -> Additions and Overrides -> Set 
"LCLWidgetType" -> Drop Down selection Value "fpgui".


Sadly in  my compiled "trunk" version 1.7 on Linux  (revision 53324), 
the <"LCLWidgetType"> drop down menu is not shown any more. So the 
available WidgetTypes (aka Interfaces) can't be easily selected .

Bug, feature or erroneous configuration on my site ?
