Remove some OCaml stuff from P-A-S

[Mehdi Dogguy <mehdi.dogguy@pps.jussieu.fr>]

Hi,

Recently, spamoracle and ara packages changed a bit. $PKG-byte packages 
have been merged into the $PKG package when ocamlopt is not available. 
Hence, they are not packages-arch-specific anymore and can be compiled 
on *any* architecture.

Could someone remove them for the P-A-S file please and give-back them 
on those architectures?

Thanks in advance,
