Yes, with minor modifications. The TLS related code in dyld is pretty 
much self contained. I don't see dyld using any functionality that isn't 
available to a regular application.

The license is a completely different issue. The safest would be to 
re-implement the code. One can document the existing code and some other 
can do the implementation.

Regardless of the license, you can still give a try to see if the 
technical parts work.

You'll just need to add a call to druntime in one of the functions in 
the dyld TLS code. Have a look at:
