I'd use this:

using gcc : 3.4 ;
using gcc : 3.4arm : /path/one/arm-g++ : <other stuff> ;
using gcc : 3.4ppc : /path/two/ppc-g++ : <other stuff> ;

and them

bjam gcc-3.4 gcc-3.4arm gcc-3.4ppc

Will be done automatically with the above.

What do you mean? Version number is basically string, you can put everything 
there. Boost.Build interprets that string in any way only for msvc, but not 
for gcc.

Well, I did not seen this method ;-)
