Re: libtool generates incorrect option for Solaris ld

[Ralf Wildenhues]

Thanks for your feedback.  Does this patch work for you?

OK to apply to both branches?  Or do you think I should hack in
$reload_cmds, or do a full link (I fear a situation where we may have to
add some extra libraries for some obscure setup)?

Cheers,
Ralf
