ELF/BFD: Limit `_bfd_elf_link_renumber_dynsyms' call in section GC

Browse Source 
Consistently call `_bfd_elf_link_renumber_dynsyms' only if linking a
dynamic binary, complementing code in `bfd_elf_size_dynsym_hash_dynstr'
and commit ccabcbe51e ("New attempt at fixing MIPS --gc-sections et
al."), <https://sourceware.org/ml/binutils/2005-08/msg00258.html>.

	bfd/
	* elflink.c (bfd_elf_size_dynamic_sections): Only call
	`_bfd_elf_link_renumber_dynsyms' after section GC if dynamic
	sections have been created.
