the sigtramp. That way we can still recognize a sigtramp if its
location is changed in a new kernel. This is especially
important for OpenBSD, since it uses a different memory layout
than NetBSD, yet we cannot distinguish between the two.
Of course this is still based on the assumption that the sigtramp
is placed directly under the location where the program arguments
and environment can be found. */
