> > +GCC has internal multilib handling code but it assumes a very

> > generic and allows
> > +complete customisation of the library directories.
> > +
> > +This patch is a partial solution to allow any custom directories to

> > +and handled correctly. It forces gcc to use the base_libdir (which
> > is the current
> > +directory, "."). We need to do this for each multilib that is

> > +know which compiler options may be being passed into the compiler.
> > Since we have a compiler
> > +per mulitlib at this point that isn't an issue.
> > +
> > +The one problem is the target compiler is only going to work for the
> > default multlilib at
> > +this point. Ideally we'd figure out which multilibs were being
> > enabled with which paths
> > +and be able to patch these entries with a complete set of correct
> > paths but this we
> > +don't have such code at this point. This is something the target gcc
