    gcc, doc: Fix Darwin bootstrap: Amend an @option command to elide a space.
    
    At least some version(s) of makeinfo (4.8) do not like @option {-xxxx}
    the brace has to follow the @option without any whitespace.
    
    makeinfo 4.8 is installed on Darwin systems and this breaks bootstrap.
    The amendment follows the style of the surrounding code.
