Well sorry about the confusion... I was thinking of the extra 
"requirements" arg that I put into darwin.jam. But that I now realize, 
forgot to put the same code into gcc.jam :-( Yes, Thomas is correct. 
What I said only applies, as given, to the darwin (xgcc) toolset. But 
you can do the same for any other toolset with a bit of "manual" labor:

import toolset ;
using gcc ;
using gcc : 4.0~arm : arm-none-linux-gnueabi-g++ ;
toolset.add-requirements 
<toolset>gcc,<architecture>arm:<toolset-version>4.0~arm ;

Or something like that.. This technique has been mentioned a few times 
in this list. So searching will reveal the actual syntax to use for 
toolset.add-requirements.
