* lexsup.c (parse_args): Set check_section_addresses to 1 or 0.
* ld.h (args_type): Make check_section_addresses a char.
ldlang.c (lang_process): Don't consider relocatable flag when
checking for overlap.
* ldmain.c (main): Default check_section_addresses to -1. Check it
for relocatable links.
* ld.texinfo (--check-sections): Update documentation.
