The nfs_autoload test case of the lib/librumphijack/t_tcpip test program
has been failing since April 2017.  The failures started during a period
of build breakage when the following commits were made:

Log output from a recent failure is at:

See http://gnats.netbsd.org/49153 for some pertinent comments from
the last time this test broke.

The test only fails on i386 because it is only enabled on i386.
