multiple cpu's with a single install

[William Baker]

I would like to support a new CPU.  It's been a very long time since I 
dug deep into the gcc emitter code.  (Think Amiga.)

Has anyone ever considered the possibility of supporting multiple CPU's 
and architectures with a single install?  I already have a small 
collection of cross compilers, and I really wish I could just say "gcc 
--cpu=arm hello.c", or "gcc --cpu=i686 hello.c".  Pipe dream?

Please forgive the slightly off-topic post.  I hang out on this list and 
really appreciate those I have come to recognize through their posts.
