It's possible that it would work, but
I wouldn't count on it. We don't do
anything to ensure it.

The only problem is that the final libraries have the same name.
You can either use --layout=tagged or --layout=versioned
to include the toolset in the library name, or you
can use --stagedir=xxx to install the libraries into
two different directories.
