[PATCH 2/3] Fix --no-undefined

[Guido Günther <agx sigxcpu org>]

Hi,
according to ld's manpage the options for listing undefined referenes is
--no-undefined (and therefore -Wl,--no-undefined when passed on from
gcc) and not -no-undefined. Attached patch fixes this.

I couldn't find the -version-info option in gcc/ld's docs either but
left it in for now since it might work on other platforms.

Cheers,
 -- Guido
