AXP (although that one is broken AFAIK), ARM (BE and LE), CRIS, i386, 
68k, MIPS (BE and LE), PPC (32 and 64 bits), SH4, and SPARC (32 and 64 
bits).

This is not what I have been talking about at all. What I was getting at 
is that you seem to think it is not possible to install packages and 
running their pre/post scripts without moving the entire build into a 
(system) emulator. This is wrong, you just have to do what I described 
above, and you can set up your sysroot on any machine. How you build the 
packages has nothing to do with that.
