    tests: Skip SIGBUS test on FreeBSD
    Currently, 'softsig-helper -buserror' causes a SIGBUS on most
    platforms, but can result in SIGSEGV on FreeBSD by default (at least
    on 11.3-RELEASE). Skip the test on FreeBSD, until we can provide a
    more reliable way to generate SIGBUS.
    Note that when the sysctl machdep.prot_fault_translation is set to 1,
    'softsig-helper -buserror' generates a SIGBUS instead of SIGSEGV,
    suggesting that generating a SIGBUS here is the old 'compat' behavior.
    When machdep.prot_fault_translation is 0 (the default), the code path
    in the FreeBSD kernel that dictates whether to send a SIGBUS or
    SIGSEGV in this situation depends on some autodetection heuristics,
    and so may produce different results depending on FreeBSD releases or
    even compiler settings (due to detection of ABI based on some ELF
    notes in the relevant binary).
    For some details on this sysctl, see
    or the FreeBSD source code. In 11.3-RELEASE, the decision to issue a
    SIGBUS or SIGSEGV can be found around sys/amd64/amd64/trap.c:355.
