When build some big package with binutils/gcc, we meet some problem about
virtual memory exhausted
on 32bit systems.
As you know the i386 has 3GiB userland virtual memory limitation, and
mips32 has only
2GiB even. 3GiB/2GiB is not enough for some big project.
For LTO in future, it also need lots of memory.
So, our plan is to figure out binutils64/gcc64 for these architectures
with multilib.
For i386, it may be:
--build i386 --host amd64 --target i386
@powerpc: does powerpc need it?
