NetBSD expects this testcase to fail with SIGBUS, but instead it fails with
SIGSEGV on FreeBSD.

This test case is new to FreeBSD and only available on
^/projects/netbsd-tests-update-12 so far..

$ svn info /usr/src/svn/ | grep ^URL:
URL: svn+ssh://ngie@repo.freebsd.org/base/projects/netbsd-tests-update-12
$ svnversion /usr/src/svn

$ sudo kyua debug -k /usr/tests/lib/libc/sys/Kyuafile
mmap_test:mmap_truncate_signal
mmap_test:mmap_truncate_signal  ->  failed: child process got SIGSEGV instead
of SIGBUS
