Alan Modra d215621ebe Reload --as-needed libraries inside groups
When a shared library appears within --start-group/--end-group ld may
only discover a need for loading the library on the second or
subsequent pass over archive libraries, as more objects are extracted.

	* ldlang.c (load_symbols): Always check flags.reload.
