Nevermind.  I've found a solution that I believe is quite good.  For the 
benefit of anyone else who may be grappling with this, here is the 
relevant section of my configure.in:

    child_type=unknown
    AC_CHECK_HEADERS(sys/ipc.h, child_type=sysipc)
    AC_CHECK_HEADERS(pthread.h, child_type=pthread)
    AM_CONDITIONAL(ENABLE_PTHREADS, test "$child_type" = "pthread")
    if test "$child_type" = "unknown"; then
      AC_MSG_ERROR([could not find an acceptable multitasking library.])
    fi

This should scale well, doesn't rely on undocumented features and even 
looks pretty.
