my previous answer targeted this second problem (as I do not have
any experience with multilib).
I'm guess the basic tools packages, like binutils and gcc, have to
support a ``bootstrap'' which involves this. But these packages are
too complex.
That's why I suggested to study texinfo/configure.ac (from version
4.8 or newer), which does build a couple of native tools, which are
then needed for the main cross-platform build.
Texinfo is a smaller package, and thus should serve as a more
comprehensive example. Feel free to ask me about the details of it.
HTH,
Stepan Kasal
