Arm: drop .bss override

The comment looks bogus (perhaps simply stale), and there are also no
other precautions against subsections being used on ELF with .bss. It
also doesn't look to be a good idea to override the custom handlers that
ELF and COFF have (afaict doing so further broke .previous on ELF).
