I am not sure what you want from crosstool-NG in this respect. If you 
are talking about the layout of the resulting filesystem, crosstool-NG 
is but a little piece - the construction of the filesystem is typically 
handled by other tools such as buildroot. Perhaps, you need to explain 
this a bit more.

It would be interesting but I am not sure how much we can safely share. 
Some host components are still configured for a particular target.
Others may be shared, but this would place certain requirements on the 
host/build configuration parts (which obviously must be the same for all 
of them).
BTW, by "out dir" do you mean the build directory or the installation 
directory?

I am not totally opposed to this, but before you start hacking around, 
I'd suggest you make a small write-up on *what* you intend to share and 
*how* you are going to check that it is actually shareable (e.g., fail? 
create a separate build directory for each different config? anything else?)
