-extI is only required on Windows.

Use -I=path --dllimport=all instead of -extI=path --dllimport=externalOnly

And it only applies when that import is for a shared library.

Note: while dmd has these switches now, it does not ship druntime/phobos 
as shared libraries so you won't be using shared libraries with it yet.
