Use offsets instead of addresses in ELF_SECTION_IN_SEGMENT for non SHT_NOBITS

Browse Source 
For sections that are not SHT_NOBITS, use sh_offset and p_offset instead of
sh_addr and p_vaddr when calculating if a section fits in a segment. Both
methods are valid when using the GNU linker.

include/
	* elf/internal.h (ELF_SECTION_IN_SEGMENT): Don’t check addresses
	for non SHT_NOBITS.
