You can use just one relocation on x86 because you have .got.plt.
The old powerpc abi has quite an unusual PLT. It is a bss section,
so the reloc needs to create the entire plt entry. See
glibc/sysdeps/powerpc/powerpc32/dl-machine.c. It seems a silly idea
to use just one reloc that does wildly different things depending
on the section to which it applies.
