I've made a little progress.
Getting a multilib build looks extremely difficult -- GCC does helpful
things like not looking in lib64 for 64-bit libraries, but *also* does
helpful things like installing stuff into lib64, even with
--disable-multilib. Compiling GCC would be funny if it wasn't so tragic.
I have managed to get up to a full install of gcc-cross, with the
attached patches (these aren't yet for wider consumption, they're just
my hacks as of today -- if this works for building more I'll clean them
up and post them properly). The key change here is to patch GCC to fake
"../lib" to be both the 64-bit and 32-bit library locations -- that
seems to be the ultimate way to convince GCC to avoid using the lib64
abomination.
For this build I'm forcing GCC version 4.2.2, glibc version 2.5, and
kernel 2.6.23.
