    [gdb/testsuite] Fix gdb.mi/mi-sym-info.exp on openSUSE Tumbleweed
    
    On openSUSE Tumbleweed, I run into:
    ...
    FAIL: gdb.mi/mi-sym-info.exp: List all functions from debug information only
    ...
    
    The problem is in matching this string:
    ...
    {name="_start",type="void (void)",description="void _start(void);"}
    ...
    using regexp fun_re, which requires a line field:
    ...
    set fun_re \
        "\{line=\"$decimal\",name=${qstr},type=${qstr},description=${qstr}\}"
    ...
    
    Fix this by making the line field optional in fun_re.
    
    Tested on x86_64-linux.
