[Boost-build] Duplicate gcc initialization

I've just tried the following:

        using gcc ;
        using gcc ;

and got this:

        error: duplicate initialization of gcc with the following parameters:
        error: version = 4.0.3

so, the gcc toolset correctly auto-detects the version, and find the compiler, 
but it fails to notice that in both 'using' cases it's the same compiler.

Should we check if exactly the same compiler is detected?
