* elflink.h (elf_link_add_object_symbols): Calling check_relocs

Browse Source 
even if SEC_ALLOC is not set.
	* elf32-i386.c (elf_i386_check_relocs): Don't check SEC_ALLOC
	when deciding whether to copy a reloc into a shared object.
	(elf_i386_relocate_section): Likewise.
	* elf32-sparc.c (elf32_sparc_check_relocs): Likewise.
	(elf32_sparc_relocate_section): Likewise.
	* elf32-i386.c (elf_i386_check_relocs): Don't set SEC_ALLOC in a
	reloc section if it is not set in the source section.
	* elf32-sparc.c (elf32_sparc_check_relocs): Likewise.
	* elf.c (bfd_section_from_shdr): Mark a reloc section associated
	with a SEC_DEBUGGING section as SEC_DEBUGGING.
