Actually, this is already LGPL (with an exception to make it even more
liberal!) for the runtime and the libraries.
So your only problem with the QPL would be if you need to modify the
compiler itself, and are not happy with the conditions of the QPL.

The QPL is an official open-source license.
There is nothing preventing you to include the compiler in your
package, as long as you make it clear that the compiler itself is
copyrighted and under the QPL.
(One question is whether you need to include all the tools and
libraries from the distribution, as the QPL seems to imply. I believe
this can be clarified with the developpers if needed.)

So I don't really see your problem...
