Treat SHT_FINI_ARRAY and SHT_PREINIT_ARRAY as relocatable sections 

Since SHT_FINI_ARRAY and SHT_PREINIT_ARRAY sections are relocatable,
this patch fixes readelf and adds a testcase.

binutils/

	* readelf.c (process_section_headers): Treat SHT_FINI_ARRAY and
	SHT_PREINIT_ARRAY as relocatable sections.

gas/

	* testsuite/gas/elf/elf.exp: Run section14.
	* testsuite/gas/elf/section14.d: New file.
	* testsuite/gas/elf/section14.s: Likewise.
