Hi Jim: Thanks for the patch! this indeed a great improvement on multilib stuffs, especially improving silently fail part, some time it will result linker error, but it won't got error if lucky enough (okay, or we could say unlucky...), the only thing I would like to improve is the test, it's only able to test with specific multilib configuration, I guess this may improve by using external spec files to override the default multilib spec, but I think that's definitely not a blocker for this patch.
LGTM, and pushed to trunk :)
