My fault.  I told James to put is_ppc_vle in elf32-ppc.c in an attempt
to keep the section flag usage private to elf32-ppc.c.  Looks like it
needs to escape or we go quite silly and make an elf backend function
just for powerpc.  Fixed like this.

bfd/
	* elf32-ppc.c (has_tls_reloc, has_tls_get_addr_call, has_vle_insns,
	is_ppc_vle): Move to..
	* elf32-ppc.h: ..here, making is_ppc_vle a macro.
opcodes/
	* ppc_dis.c: Don't include elf/ppc.h.
