Fix internal error on library-level type extended locally
The compiler aborts on the local extension of a tagged type declared
at library level, with a progenitor given by an interface type having
a primitive that is a homograph of a primitive of the tagged type.
gcc/ada/ChangeLog:
* gcc-interface/trans.c (maybe_make_gnu_thunk): Return false if the
target is local and thunk and target do not have the same context.
