ada: Fix ALI elaboration flags for ghost compilation units (cont.)

When GNAT was compiling a ghost unit, the ALI file wrongly suggested that this
unit required elaboration counters, which caused linking errors to non-existing
objects.

gcc/ada/ChangeLog:

	* sem_ch10.adb (Analyze_Compilation_Unit): Ignored ghost unit need no
	elaboration checks.
