Omit section dynsyms for any linker created section

Browse source 
This is a simplification, and fixes a testcase I had where an empty
powerpc64 .branch_lt section was chosen for the data_index_section
dynamic symbol and thus wasn't removed.

	* elflink.c (_bfd_elf_link_omit_section_dynsym): Return true for
	any output section matching a linker created dynobj section.
