Fix a potential illegal memory access when testing for a special LTO symbol name.
bfd * linker.c (_bfd_generic_link_add_one_symbol): Test for a NULL
name before checking to see if the symbol is __gnu_lto_slim.
* archive.c (_bfd_compute_and_write_armap): Likewise.
binutils
* nm.c (filter_symbols): Test for a NULL name before checking to
see if the symbol is __gnu_lto_slim.
* objcopy.c (filter_symbols): Likewise.
