The 32bit system has 2GiB/3GiB virtual memory space limitation.
When a big object file need to compile/link, the ld/gcc/cc1 may need lots of
memory, which may be more than 2GiB/3GiB.

So, we need a toolchain which in fact is running on 64bit env,
while output 32bit object by default.
That's what multilib can help us.
