[ppc32] Make inline plt reloc "unsupported for bss-plt" an error

[Alan Modra]

This was always supposed to be an error.  Code emitted by gcc for
inline PLT calls assumes PLT is an array of addresses.

	* elf32-ppc.c (ppc_elf_relocate_section): Add %X to "unsupported
	for bss-plt" warning to make it an error.
