Hi Rene !

This commit just broke my builds :-))

So whats wrong:
First, my user-config.jam sets up my gcc-wrapper-script (for icecc and 
STLfilt) like

using gcc : 4.1 : /home/hunold/bin/gcc-4.1.sh
And to find out more about the compiler you simply called:

I propose to call "SHELL $(command) --version" for support of non-standard gcc 
names. Please find the patch attached.
This is important because on debian for example, you can have several gcc 
installed in parallel, the non default compilers are then 
named /usr/bin/gcc-3.3 and so on. Those won't be usable, too.

Another fact is that I now get "gcc-suse_linux-4.1" instead of a 
simple "gcc-4.1" but I can live with that ;-))

But it would be nice if BBv2 could detect the target architecture and adjust 
build paths accordingly.

That would mean that for:

Target: x86_64-suse-linux

it would extract x86_64 on Linux.
