Fine. I'm now going to try to build a 64-bit glibc (and worry where to

chicken-and-egg-problem creeping up to me - wouldn't I need 64-bit
support in my compiler to create the corresponding glibc?
D'oh!
Any pointers, docs or howtos anyone? Much appreciated!
It sounds like you want to look into how to build a cross-compiler. I've
never attempted to do so, but surely there is documentation on how to
bootstrap a cross compiler targeting a clean environment.
(As far a binutils, since you want cross-binutils, you are building
32-bit binaries - i.e. your existing compiler is fine - that will
generate 64-bit binaries. I'm not sure about libc, I guess it must be
possible to build a "bare metal" cross compiler that you can use to
build a libc; maybe you have to build a bare metal cross compiler first
and then a cross compiler that uses that libc.)
Apologies for the not-very-helpful answer, but maybe this will at least
point you in the right direction to go looking for further information.
