Yes, there are other places missing TO_ADDR, and one of the minfo
lines wrongly invokes TO_ADDR.  Thanks for the prod.

	* ldlang.c (TO_ADDR, TO_SIZE, opb_shift): Move earlier in file.
	(lang_insert_orphan): Use TO_ADDR in __stop sym calculation.
	(print_input_section): Don't use TO_ADDR when printing section
	size.
	(lang_size_sections_1): Use TO_ADDR in overlay lma calculation.
	(lang_size_sections): Use TO_ADDR in relro end calculation.
