commit aa19c68d2bdf3a831894f609b8ac5c8f123268b2
Author: Sergey Bugaev <bugaevc@gmail.com>

    hurd: Use __mach_setup_thread_call ()
    
    ...instead of mach_setup_thread (), which is unsuitable for setting up
    function calls.
    
    Checked on x86_64-gnu: the signal thread no longer crashes upon trying
    to process a message.
