ppc32 merging of e_flags from dynamic objects

EF_PPC_RELOCATABLE and similar flags, if present in an input shared
library, don't have any relevance as far as the output file is
concerned.

Currently, dynamic objects aren't seen in merge_private_bfd_data.
This patch is in preparation for a change to that.

	PR 25882
	* elf32-ppc.c (ppc_elf_merge_private_bfd_data): Ignore e_flags
	from shared libraries.
