The design of multiarch is so that you can install the arm deb on arm
and compile or unpack it into a chroot and cross-compile or even install
it in your real system and cross-compile there.
The big change will be that you no longer need to compile a bunch of
cross compile libraries but you can just use the debian packages as is.
Also you probably want a build chroot. In there you need the native libs
and tools and a cross-compiler. Do you then want to have a chroot in the
chroot for the foreign libs? Or a single multiarch chroot for the native
tools, cross-compiler and foreign libs?

Setting the link different is simple. But then you need to edit the .pc
file as well. It adds up.
