 It's not clear what else GCC skips from reading manpage and whether it
 affects -pthread option.

 Note: -lpthread is only present when -nostdilb is *not* specified.
 
 I'm not sure why we should invent even more hacky way to solve -nostdlib
 issue. I think my REINPLACE_CMD hack is simple enough. And we can
 probably drop BROKEN on 6.x, too.
 
 The interesting question is how other ports that have -nostdlib but need
 threading support handle it.

 BTW, pre-everything target should probably be hidden behind WITHOUT_X11 ifdef.
