I inentionally punted on that issue because Symbian has raised that 
issue for discussion by the ARM ABI group.  The BPABI doesn't presently 
specify these symbols, but Symbian is requesting that it should.  ARM's 
toolchain generates these symbols, which is why SymbianOS depends on 
them; it's very likely that other BPABI platforms (PalmOS) do, but I 
have no direct evidence one way or the other.

Also, there's a ton of stuff in that linker script that's just copied 
from generic GNU ELF, but really need not be there on BPABI platforms. 
I'm not sure exactly how to handle that; we could aggressively rip it 
out, but then we might rip out too much.  I can't quite decide whether 
it's better to be like the generic ELF configuration (so that it's easy 
to add things in both places) or better to be minimal (so that it's easy 
to understand the BPABI script).
