[Boost-build] getting the compiler command inside jamfile

Hi,

I already posted the question on stackoverflow 
(http://stackoverflow.com/questions/30550071/boost-build-get-compiler-command) 
but asking in the mailing-list is smarter.

I want to add a compiler command, because I am building for a none eabi 
embedded device. That is the compiler command is "arm-none-eabi-g++" and 
I already got that to work, quite easily.
Now the question: how do I get the command in the jamfile, because I 
want to add the commands needed for embedded devices, which share the 
prefix, that is "arm-none-eabi-objcopy" and "arm-none-eabi-size". Now I 
want it to be portable (that is other architecture), so I need to deduce 
the prefix from the chosen toolset, i.e. find out "arm-none-eabi-".
I don't really want to change the gcc.jam for that.
Can anyone help me?

Thanks,

Klemens
