Or provide optionally a 64b kernel and keep the same 32b user-space?
That's what we do for sparc64.
On x86_64, this would solve the memory limit issue.

Only for binutils and gcc, before compiling the kernel, we add a stage where
we cross-compile another binutils/gcc. No lib is cross-compiled.

Supplemental work is very minimal.
I don't know if it's clean to do this way but this is reported to work.
The only problem I know actually is that I was not able to run make check on
