No! AFAIK, that's what we havef today.

I meant

<target-platform>linux # building objects for linux
<toolset>intel # using an intel compiler

The target platform and the compiler are orthogonal; I see no reason
to bind them together. At some point you might want to do
cross-compilation... so it's not clear whether intel's different
options should be associated with the source-platform or the
target-platform, since they don't support cross-compilation (yet).
