This PR is about another issue, which I discovered during debugging of
the gptzfsboot problem.

The actual problem when compiling (gpt)zfsboot with clang and -mrtd
seems to be that clang screws something up with the function calling
conventions, causing crashes and other weird things.  I have not yet
determined the root cause of this.
