[Ecls-list] Help needed, really

Why not check what information is put in *features* by other 
implementations?  If OpenAxiom runs on them, then that should be enough.

Keywords like :X86 and :X86-64 seem common, and this should be easy to 
figure out when building ECL.  :ILP32 or :LP64 might be even more 
informative than that.  Since ECL depends on a C compiler, maybe an 
additional :GCC or :SUNCC or whatever keyword identifying the compiler 
would be useful too.

Clozure CL has target and host endianness and word size information.  
Armed Bear CL will tell you what Java version (1.5 or 1.6) it is running 
on.  Even CLisp (which IIRC compiles to portable bytecode) says 
something like :PC386.

This information is useful, can usually be figured out at build time, 
and is harmless to put in *features*.
