PowerPC64 synthetic symbols

If an assembler trims off unused section symbols there may be no
section symbols.  This means that testing for the .opd section symbol
needs to test both the section name and symbol flags.

	* elf64-ppc.c (ppc64_elf_get_synthetic_symtab): Don't assume
	section symbols are present.
