    Fixes powerpc64le ld segfaults when --emit-relocs is used.
    
    ELFv2 needs fewer relocs to annotate plt call stubs.  I correctly
    allocated a smaller buffer and wrote the proper relocs, but stupidly
    bumped the reloc count as for ELFv1.
    
    	* elf64-ppc.c (ppc_build_one_stub): Correct reloc count passed
    	to get_relocs for ELFv2.
