SHT_SYMTAB_SHNDX handling
.symtab_shndx section contents is an array, one entry for each symbol in .symtab, present when the number of symbols exceeds a little less than 64k. Since the mapping is 1-1 with symbols there is no need to keep both dest_index and destshndx_index in elf_sym_strtab. Instead, just make sure that the shndx pointers to the swap functions are kept NULL when .symtab_shndx does not exist. Also, strtabcount in the linker's elf hash table is incremented in lock-step with the output symcount, so that can disappear too.
