Okay --- that works.  Here's the latest iteration:

---
load_base_board_description "unix"

set strip_to_file_program "/home/jimb/elfutils/bin/strip"

proc ${current_target_name}_compile {source dest type options} {
    global strip_to_file_program

    # Run the standard compilation procedure.
    set result [default_target_compile $source $dest $type $options]

    # If it didn't succeed, return directly.
    if {[string compare $result ""] != 0} {
        return $result
    }

    # Otherwise, strip the executable and copy its debug info to a
    # separate file, leaving only a pointer behind.
    if {[string compare $type executable] == 0} {
        exec $strip_to_file_program -f ${dest}.separate-debug ${dest}
    }
}

proc ${board}_init { whole_name } {
    global board_info
    set board_info(unix-separate-debug,isremote) 0
}
